How do you find the arithmetic exception?

You can catch different exceptions in different catch blocks. When an exception occurs in try block, the corresponding catch block that handles that particular exception executes. For example if an arithmetic exception occurs in try block then the statements enclosed in catch block for arithmetic exception executes.

Is arithmetic exception a runtime exception?

3 Answers. ArithmeticException is a subclass of RuntimeException, meaning that it would already be handled by the catch (RuntimeException e) branch. The compiler error is because the broader exception should be caught last.

What is the subclass of arithmetic exception?

ArithmeticException is a subclass of java. lang. Exception, by time the ArithmeticException has been specified it has already been caught by the Exception class. If ArithmeticException appears before Exception, then the file will compile.

How do you raise arithmetic exception in Java?

We can define our own set of conditions or rules and throw an exception explicitly using throw keyword. For example, we can throw ArithmeticException when we divide number by 5, or any other numbers, what we need to do is just set the condition and throw any exception using throw keyword.

What is exception in Java with example?

A Runtime error is called an Exceptions error. It is any event that interrupts the normal flow of program execution. Example for exceptions are, arithmetic exception, Nullpointer exception, Divide by zero exception, etc. Exceptions in Java are something that is out of developers control.

What is arithmetic operator in Java?

The Java programming language supports various arithmetic operators for all floating-point and integer numbers. These operators are + (addition), – (subtraction), * (multiplication), / (division), and % (modulo). The integer is implicitly converted to a floating-point number before the operation takes place.

What are the types of exceptions in Java?

Types of Exception in Java with Examples

  • ArithmeticException. It is thrown when an exceptional condition has occurred in an arithmetic operation.
  • ArrayIndexOutOfBoundsException.
  • ClassNotFoundException.
  • FileNotFoundException.
  • IOException.
  • InterruptedException.
  • NoSuchFieldException.
  • NoSuchMethodException.

Is FileNotFoundException checked or unchecked?

FileNotFoundException is a checked exception in Java. Anytime, we want to read a file from the filesystem, Java forces us to handle an error situation where the file may not be present in the place. In the above example, you will get compile-time error with the message – Unhandled exception type FileNotFoundException.

What is FileNotFoundException in Java?

java.io.FileNotFoundException. Signals that an attempt to open the file denoted by a specified pathname has failed. This exception will be thrown by the FileInputStream, FileOutputStream, and RandomAccessFile constructors when a file with the specified pathname does not exist.

How many exceptions are there in Java?

There are three types of exception—the checked exception, the error and the runtime exception.

What kind of error is arithmetic exception?

Introduction to Java ArithmeticException. Java Arithmetic Exception is a kind of unchecked error or unusual outcome of code that is thrown when wrong arithmetic or mathematical operation occurs in code at run time.

Why do we use super in Java?

The super keyword in java is a reference variable that is used to refer parent class objects. Basically this form of super is used to initialize superclass variables when there is no constructor present in superclass.

How do you handle exceptions in Java?

The try-catch is the simplest method of handling exceptions. Put the code you want to run in the try block, and any Java exceptions that the code throws are caught by one or more catch blocks. This method will catch any type of Java exceptions that get thrown. This is the simplest mechanism for handling exceptions.

Java ArithmeticException

An uncontrolled mistake or odd consequence of code is thrown when a faulty arithmetic or mathematical operation happens in the code during runtime, and this is known as a Java Arithmetic Exception. When the denominator is the integer zero, a runtime issue, commonly known as an exception, occurs. Because the JVM is unable to evaluate the result, the program’s execution is halted and an exception is thrown, which is documented here. The program quits at the point where the exception is thrown, but code that occurs up to that point is run and the result is shown.

Structure of ArithmeticException in Java

ArithmeticException: Structure of the base Class ArithmeticException:

Constructor of ArithmeticException

One example is the ArithmeticException() function, which defines an Arithmetic Exception with no parameters supplied or with no specific message. Calculate an ArithmeticException with one parameter supplied to ArithmeticException(String s). The detailed message is denoted by the letter s:s.

How ArithmeticException Work in Java?

The following are the two scenarios that might result in a Java ArithmeticException being raised:

  • A number divided by Zero that is not defined and is also an integer
  • Big Decimal generates non-terminating long decimal numbers.

1. Division of a Number by an Integer Zero

It is possible in Java to get an arithmetic exception while attempting to divide an integer by zero. The following is an example of java code to demonstrate the operation: Code in Example 1: package com.java.exception;public class com.java.exception ArithmeticException System.out.println(“Division has been successfully completed”);System.out.println(“Value after division: “+c);public static void main(Stringargs)ArithmeticException ex=new ArithmeticException();ex.division(10,0);

  • / by zero: This is the detailed message given to the class ArithmeticException while generating the ArithmeticException instance
  • Lang.ArithmeticException: This is an exception thrown by the Java programming language during division
  • / by zero: This is the detailed message given to the class ArithmeticException while generating the ArithmeticException instance

As a result of dividing 10 by 0, where 0 is an integer and is undefined, the arithmetic exception described above is thrown. /package com.java.exception;public class com.java.exception;public class ArithmeticException void division is a division that does not exist (int a,int b) System.out.println(“Division of a number is successful”);System.out.println(“Output of division: “+c);public static void main(Stringargs)ArithmeticException ex=new ArithmeticException();ex.division(10,5)

2. Non-Terminating Long Decimal Numbers by Big Decimal

Java has a BigDecimal class that can represent decimal values with a large number of precision digits and a big number of precision digits. There are several functions in this class of java that are not present in the primitive data types, such as integers, doubles, and floats, which include the following: These features allow you to round off the decimal numbers in a variety of ways. For the sake of demonstration, the following code is provided: Code for Example1: /package com.java.exception;import java.math.BigDecimal;public class ArithmeticException;public static void main(Stringargs)BigDecimal a=new BigDecimal(1);BigDecimal b=new BigDecimal(6);a=a.divide(b);System.out.println(a.toString());a=a.divide(b Output: Because the huge decimal class in the java code above is unsure of what to do with the division output, it throws or displays an arithmetic exception in the output console in the example above.

With the descriptive warning “Non-terminating decimal expansion, no accurate representation,” it throws an exception.

When computing c, for example, the number should be restricted to 7 decimal places by rounding the number up to the 7thdecimal precision value.

How to Avoid or Handle Java ArithmeticException?

Exception handling is the process of dealing with the exceptions raised by the Java virtual computer. The advantage of exception handling is that the code’s execution does not come to a complete stop. Exceptions are handled by employing a mix of the try and catch statements. A try/catch block is added to any function that has the potential to create an exception. In programming, protected code is code that is written inside of a try/catch statement. Syntax: try (set of statements/protected code) catch (exceptionname except) catch (exceptionname except) catch (exceptionname except) catch (exceptionname except) catch (exceptionname except) catch (exceptionname except) catch (exceptionname except) catch (exceptionname except) catch (exceptionname except)

ArithmeticException Handling using tryCatch Blocks

  • Write try and catch blocks around the statements that may cause an ArithmeticException to occur. When an exception occurs, the execution is sent to the catch block, which is located at the point of the exception’s occurrence. It then runs the catch block statement and moves on to the statement that was present after the try and catch blocks were completed. The following is an illustration:

Code: public class ExceptionHandledpublic static void main(String args)int x = 100, y = 0;int z;System.out.println(“Hello world”);tryz = x/y;System.out.println(z);catch ExceptionHandled(); (ArithmeticException except) System.out.println(“Avoid dividing by integer 0” + except);System.out.println(“Hello class”);System.out.println(“Hello there”);System.out.println(“Avoid dividing by integer 0” + except); In addition to Hello world, the output console displays Hello class and Hello, which are also written on the screen.

Exceptions are handled in this manner as a result of the technique.

  1. Try and catchblocks are exception handling keywords in Java that are used to thoroughly address an exception or unchecked error that has been raised in the code without causing the execution to halt. Identify the statements that are causing problems and insert them in the try block. When the try block throws an exception, the catch block takes care of it, and the program’s execution continues on to the final statement in the loop. Alternatively, if the try block does not raise an exception, the catch block is simply ignored. Ensure that the catch block contains an appropriate exception handler or statements in order to effectively manage or detect the exception raised by the try block.

Conclusion

In this tutorial, you learnt about the java arithmetic exception and how to handle the exception within a try and catch block, among other things. The majority of the time, an arithmetic exception happens as a result of the division of a number by the integer 0. For the sake of this essay, I have utilized a single catch for a single attempt; however, we may use multiple catch for a single try as well.

ArithmeticException in Java – Causes & Treatment

The purpose of this lesson is to provide you with a few examples that will help you understand the reasons why an ArithmeticException is produced within a Java program. We will talk about the most prevalent reasons of exceptions and how to deal with them in the future.

What is an ArithmeticException?

In computer science, an arithmetic exception refers to an error that happens when an improper arithmetic condition arises. This often occurs when a mathematical calculation error occurs within a program during run-time, as opposed to during development. Typically, this is a mathematical condition that Java is unable to deal with well. In the following sections, we will go over the various reasons of an ArithmeticException and how to deal with them.

Dividing by a zero value integer

In computer science, an arithmetic exception refers to an error that happens when an improper arithmetic circumstance arises in a program. A mathematical calculation mistake occurs within a program during run-time, and this is the most common cause of this.

A typical example is a mathematical scenario that Java is unable to handle. In the following sections, we will go over the many reasons of an ArithmeticException and how to avoid them.

Non-terminating decimal numbers using BigDecimal

The BigDecimal class is a Java class that is used to represent decimal numbers with a large number of precision digits, up to a very large number of precision digits. Additionally, the class provides a number of features that are not available when working with simple data types such as doubles and floats. Rounding up or down a number, determining the amount of decimal places we require from a number, and so on are examples of these features. Because BigDecimals are used to represent numbers with a high degree of accuracy, it is possible that a problem will arise when dividing particular numbers, for example, when dividing 1 by 3, or when dividing 2 by 12 These numbers do not have a set number of decimal places, for example, 1/3 = 0.33333333333333333333333333333333333333333.

Consider the following software as an illustration.

Exception occurred in the thread “main” java.lang.

at java.math.BigDecimal.divide(BigDecimal.java:1603)at ArithmeticExceptionExamples.main at java.math.BigDecimal.divide(BigDecimal.java:1603)at ArithmeticExceptionExamples.main (ArithmeticExceptionExamples.java:10) The following is the result of the Java program: 1 Given that the software is unsure of what it is supposed to do with the division result, an exception is thrown with the message “Non-terminating decimal expansion.” This is due to the fact that the result has an indeterminate number of decimal places.

One possible solution to the aforementioned difficulty is to specify the number of decimal places we require from the result, as well as the type of rounding that will be used to limit the value to a specific number of decimal places, before running the program.

big decimal;public class import java.math.BigDecimal; The ArithmeticExceptionExamples package contains the following classes: public static void main (String args) In this case, we restrict the number of decimal places to one.

System.out.println(x.toString()); System.out.println(x.toString()); The program runs correctly in this case because we specified a limit on the amount of decimal places that the variable “x”could take on in the first place. 0.3333333

ArithmeticException Java?

Exceptions have types, and being able to look up the type and instantly identify the problem is a great benefit of using exceptions. According to the documentation: In this case, the exception will be thrown when an uncommon mathematical situation has happened. For example, the integer “divide by zero” will result in an instance of this class being thrown. Furthermore, most exceptions are provided with a message to assist you in determining what went wrong even more thoroughly. try int I = 0 / 0; catch (ArithmeticException e) e.printStackTrace(); int I = 0 / 0; int I = 0 / 0; As a result, this prints:java.lang.ArithmeticException: division by zero at But how did this come to be?

JLS 15.17.2 Division Operator /

The binary/operator divides two operands and returns the quotient of the two operands as a result. The dividend is represented by the left-hand operand, while the divisor is represented by the right-hand operand. Integer division moves the decimal point closer to zero. It is possible to get anArithmeticException if the value of the divisor in an integer division is equal to zero. If you are unfamiliar with integer division, the following information may come as a surprise: System.out.println(1/2); / puts “0” in the system output.

  1. It is important to remember that anint may only contain whole integers (of limited range, some 4 billion numbers approximately).
  2. It is necessary to use a specific suffix for numeric literals in order to declare that they are double-precision values.
  3. Adoublevalue must be saved in adoublevariable in order for it to be used.
  4. It is necessary to use an explicit cast!
  5. It is solely dependent on the type of dividend and divisor being used.
  6. System.out.println(.2D +.7D -.9D); / prints “-1.1102230246251565E-16” System.out.println(.2D +.7D -.9D); / prints “-1.1102230246251565E-16” What about my code, though?
  7. As a consequence, timeTaken/1000 is equivalent to integer division.
  8. It doesn’t matter if timeInSecs is a double or a float at this point because the integer division has already been completed in the meanwhile.
  9. However, based on the error you receive, it can be determined that timeInSecsis most certainly of the integer type.
  10. So, what can we do to rectify the situation?

• timeTaken = stopTime – startTime; timeInSecs = timeTaken/1000D; speed = 45D/timeInSecs; / The letter D is not required here, but it helps to make the equation more understandable.

Java Exception Handling examples

In this article, we will look at a few examples of exceptions that are regularly seen. Looking for an exception handling tutorial? Check out this comprehensive guide:Exception handling in Java.

Example 1: Arithmetic exception

Class:Java.lang.ArithmeticException This is a built-in class that is available in the java.lang package. This exception happens when an integer is divided by zero, as in the following example. class public static void main(String args) try int num1=30, num2=0; int output=num1/num2; System.out.println (“Result: “+output); catch(ArithmeticException e) System.out.println (“You shouldn’t divide a number by zero”); It is not recommended to divide an integer by zero. Explanation: In the preceding example, I’ve divided an integer by a zero, and as a result, anArithmeticException has been generated.

Example 2: ArrayIndexOutOfBounds Exception

Class:Java.lang.ArrayIndexOutOfBoundsException When you attempt to access an array index that does not exist, you will receive this exception. For example, if an array has only five elements and we attempt to display the seventh element, an exception will be thrown. public static void main(String args); /Array has only 10 elements; catch(ArrayIndexOutOfBoundsException e); System.out.println (“ArrayIndexOutOfBoundsException”); ExceptionDemo2 public static void main(String args); try int a =new int; /Array has only 10 elements; Output:ArrayIndexOutOfBounds In the above example, the array is initialized to contain just ten entries, with indices 0 through nine.

Example 3: NumberFormat Exception

Class:Java.lang.ArrayIndexOutOfBoundsException When you attempt to access an array index that does not exist, you will see this error message. It would produce an exception, for example, if an array has only five elements and we try to display the seventh element. /Array has only 10 elements, so try int =new int; /Array has only 10 elements, so try int =new int; /Array has only 10 elements, so try int =new int; /Array has only 10 elements, so try int =new int; /Array has only 10 elements, so try int; /Array has only 10 elements, so try int; /Array has only 10 elements, so try int; ExceptionDemo2 Output:ArrayIndexOutOfBounds As shown above, the array is initialized to contain just ten entries, numbered from zero to nine.

In this case, the application is throwing an error because we are attempting to access the element at index 11.

Example 4: StringIndexOutOfBound Exception

Class:Java.lang. StringIndexOutOfBoundsException

  • When an index of a string is triggered that is not within the range, an object of this class is generated
  • This is the default behavior. In a string object, each character is kept at a certain index, which starts at 0. We may use the java.lang class’s charAt(int) function to retrieve a character that is present at a specific index in a string. Stringwhere the index is represented by the int parameter
You might be interested:  Which Is An Arithmetic Sequence? (Correct answer)

Every time an index of a string is executed that does not fall within the range, an object of this class is generated. In a string object, each character is kept at a certain index, which begins at 0. Using the java.lang class’s charAt(int) function, we may retrieve a character that is present at a specific index in a given string. Stringwhere the index is represented by the int parameter.

Example 5: NullPointer Exception

Java.lang.NullPointerException is a kind of exception in the Java programming language. When a member of this class is executed with a “null” object, a new instance of the class is generated. class Exception2 public static void main(String args) tryString str=null;System.out.println (str.length());catch(NullPointerException e)System.out.println(“NullPointerException.”);catch(NullPointerException e)System.out.println(“NullPointerException.”);catch(NullPointerException e)System.out.printl The length() method is the one that should be used on an object in this case.

However, in the above exampleStringobject str is null, indicating that it is not an object, resulting in a NullPointerException being thrown.

Types of Exception in Java with Examples

Java specifies a number of different sorts of exceptions that are related to the various class libraries available in the language. Java also provides the ability for users to create their own exceptions. Exceptions that are built in Built-in exceptions are exceptions that are present in Java libraries and cannot be overridden. These exceptions are appropriate for providing explanations for certain mistake scenarios. The following is a list of the most important built-in exceptions in the Java programming language.

  1. ArithmeticException It is thrown when an extraordinary circumstance occurs during an arithmetic operation
  2. However, it is not always thrown. ArrayIndexOutOfBoundsException When this exception is issued, it indicates that an array has been accessed with an invalid index value. The index is either negative, larger than or equal to the size of the array, or it is both. ClassNotFoundException Whenever we attempt to visit a class whose definition cannot be found, we will receive this Exception. FileNotFoundException This Exception is thrown when a file is not available or cannot be opened. IOException When an input-output operation fails or is stopped, this exception is issued. InterruptedException A thread that is waiting, sleeping, or performing some task is interrupted, resulting in this exception being raised. NoSuchFieldException A field (or variable) not found error is raised when a class does not include the field or variable requested. NoSuchMethodException It is thrown when an attempt is made to access a method that cannot be found. NullPointerException When attempting to refer to the members of a null object, this exception is thrown. Null is a symbol for nothing. NumberFormatException Whenever a method fails to convert a string into numeric representation, an exception is thrown
  3. For example, RuntimeException This class represents every exception that happens during the course of a program’s execution. StringIndexOutOfBoundsException This exception is produced by methods of the String class to signal that an index is either negative or higher than the length of the string.

Examples of Built-in Exceptions include the following:

Java

ClassArithmeticException Democatch(ArithmeticException e) is a catch-all class for arithmetic exceptions. Can’t divide an integer by zero as a result of the output

Java

This is the output of ClassNullPointer Democatch(NullPointerException e): NullPointerException.

Java

NullPointerException is thrown by the class NullPointer Democatch(NullPointerException e).

Java

The following classes are imported: importjava.io.FileNotFoundException; importjava.io.FileReader; importjava.io.FileReader; classFile notFound Democatch(FileNotFoundException e); importjava.io.FileReader; The following message is displayed: “File does not exist.”

Java

NumericFormatException e is caught by the ClassNumberFormat Democatch function. Exception in the number format in the output

Java

ClassArrayIndexOutOfBound Democatch(ArrayIndexOutOfBoundsException e) is a catch-all function for ArrayIndexOutOfBoundsExceptions. Output: The index of the array is out of bounds. Exceptions that are defined by the user The built-in exceptions in Java are not always capable of accurately describing a particular circumstance. The user can also generate exceptions in such situations, which are referred to as ‘user-defined Exceptions’. The following procedures should be taken in order to create a user-defined exception.

  • The exception class should be created as a subclass of the Exception class by the user. Because all exceptions are subclasses of the Exception class, the user should make his or her own class a subclass of the Exception class. This is accomplished in the following ways:

In order to use exception classes, the user needs develop a subclass of the Exception class. The user should create his or her class a subclass of the Exception class, because all exceptions are subclasses of the Exception class. The following are the steps to follow:

  • In his own exception class, we may define a default constructor that will be called by default.

MyException()

  • In addition, we may design a parameterized constructor that takes a string as an argument as well. We may use this to hold information about exceptions. We may use this to call the constructor of the super class(Exception) and provide the string to it.

str = super(String str); MyException(String str);

  • A user-defined exception must be raised by creating an object that belongs to his exception class and throwing it using the throw clause, as follows:

The variable MyException me is equal to new MyException(“Exception details”); hurl me to the ground;

  • Create your own exception class MyException using the following application, which demonstrates how to do so. Account numbers, client names, and balance amounts are stored in three arrays, each of which has a single row of information. The for-loop used in the main() function is used to show the information. At this point, it is determined whether any account has a balance that is less than the minimum level required to maintain eligibility for the account. If this is the case, MyException is thrown, and the message “Balance amount is less” is displayed on the screen.

Java

A RunTime Error occurred when executing the code in the class MyExceptionextendsException: privatestaticString name=; privatestaticdoublebal=; MyException()MyException(String str)publicstaticvoidmain(Stringargs)catch(MyException e) MyException: The balance at MyException.main is less than 1000 dollars (fileProperty.java:36) Output: ACCNOCUSTOMERBALANCE 1001Nish10000.0 1002Shubh12000.0 1003Sush5600.0 1004Abhi999.0 1001Nish10000.0 1002Shubh12000.0 1003Sush5600.0 Articles that are related:

Arithmetic exception In Java – Class java.lang.ArithmeticException

What Exactly Is the Arithmetic Exclusion? When an extraordinary arithmetic circumstance occurs, this exception is thrown. For example, the integer “divide by zero” will result in an instance of this class being thrown. The purpose of this lesson is to walk you through a few scenarios that will help you understand why you are encountering anArithmeticException in a Java application. In addition, we will explore the most prevalent sources of Arithmetic exceptions as well as how to deal with these exceptions.

There are many different reasons for an ArithmeticException to occur; the following are just a few of them: In Java, a list of all erroneous operations that result in an ArithmeticException() is maintained.

  • Dividing by a positive integer
  • Dividing by a negative integer BigDecimal is used to represent non-terminating decimal numbers.

dividing by a whole number Java raises an Arithmetic exception when a calculation attempt is made to divide by zero, where the zero is an integer, and the result is zero. Consider the following piece of code as an illustration: Computational ExceptionEx is a public class in the co.java.exception package. Its members include void divide(int a,int b) and int q=a/b. Its members also include System.out.println(“Successfully Divided”); System.out.println(“The Value After Divide Is:-” +q); and System.out.println(“The Value After Divide Is:-” + public static void main(Stringargs) ArithmaticExceptionEx obj=new ArithmaticExceptionEx(); obj.divide(10, 0); ArithmaticExceptionEx obj=new ArithmaticExceptionEx(); obj.divide(10, 0); When we try to run the code, we receive the following error message: Exception occurred in thread “main” of type java.lang.

  • At co.java.exception, an ArithmeticException was thrown: / by zero.
  • ArithmaticExceptionEx.main(ArithmaticExceptionEx.java:14) Because we divided 10 by 0 (where 0 is an integer), java throws the exception shown above.
  • In this case, no exception is thrown, and the variable “Q” now has the value infinite.
  • BigDecimal can be used to represent non-terminating decimal numbers.
  • Additionally, the class provides a number of features that are not available when working with simple data types such as doubles and floats.

Because BigDecimals are used to represent numbers with a high degree of accuracy, it is possible that a problem will arise when dividing particular numbers, for example, when dividing 1 by 3, or when dividing 2 by 12 These numbers do not have a set number of decimal places, for example, 1/3 = 0.33333333333333333333333333333333333333333.

  1. Exception occurred in the thread “main” java.lang.
  2. ArithmeticException: co.java.exception was thrown at java.math.BigDecimal.divide(Unknown Source) in co.java.exception.
  3. As an alternative solution to the aforementioned difficulty, we may describe the number of decimal places we require from a huge decimal, as well as the type of rounding that will be used so that the value is limited to a specific number of decimal places.
  4. package public static void ArithmeticExceptionExamples; import java.math.BigDecimal; import co.java.exception; public static void main; public static void main (Stringargs) / TODO: Create an auto-generated method stub.

System.out.println(x.toString()); / System.out.println(x.toString()); As a result, the program works correctly in this case because we set a limit on the number of possible positions for the variable “x.” Feel free to post any questions or concerns in the Comments Section. Thanks for reading!

ArithmeticException Class (System)

by an integer is a division operation. An Arithmetic exception is raised when a computation attempt is made to divide by zero, where zero is an integer, and the zero is an integer. As an illustration, consider the following piece of code: Computational ExceptionEx is a public class in the co.java.exception package. Its members include void divide(int a,int b) and int q=a/b. Its members also include System.out.println(“Successfully Divided”); System.out.println(“The Value After Divide Is:-” +q); and co.java.exception.

  1. When ArithmaticExceptionEx.divide(ArithmaticExceptionEx.java:7) is called, it is thrown at the level of co.java.exception.
  2. In contrast, if the zero is represented as a floating-point number, like in the following code, we have an entirely different outcome.
  3. Remember that dividing by zero is usually always a terrible decision, even when no exception is raised.
  4. Using the BigDecimal class, which is a Java class, you can express decimal numbers with a very large number of precision digits, up to a very large number of precision digits.
  5. Rounding up or down a number, determining the amount of decimal places we require from a number, and so on are examples of such features.
  6. These numbers do not have a set number of decimal places, for example, 1/3 = 0.33333333333333333333333333333333333333.
  7. packaged in the java exception package; imported from the math package; and a public class co.java.exception; public class The ArithmeticExceptionExamples class has the following members: public static void main (Stringargs) A stub for a BigDecimal(1) and a BigDecimal(3).
  8. Given that the division result is undefined in the class in question, an exception is thrown in the program above.
  9. java.lang.
  10. co.java.exception was thrown at java.math.BigDecimal.divide(Unknown Source).

If we declare that z should be limited to 7 decimal places, we might round up at the 7th decimal place to get the following: package public static void ArithmeticExceptionExamples; import java.math.BigDecimal; import co.java.exception; public static void main; (Stringargs) / TODO: construct a stub for the method.

Printing the value of x to the standard output (System.out.println(x.toString()); Because we set a restriction on the amount of positions that the variable “x” can take, the program executes correctly in this situation.

Definition

The exception that is thrown when an arithmetic, casting, or conversion operation fails due to a mistake.

In this article

Arithmetic is a public reference class. Exception: There is an exception. ArithmeticException is a public reference class that implements SystemException. ArithmeticException is a public class that represents an exception. SystemException is a public class that represents the ArithmeticException. SystemException is a public class that represents the ArithmeticException. ArithmeticException is a public class that represents the SystemException type Arithmetic. Exception = inheriting from a class Arithmetic of the Exception Type Exception = inheriting from a class Arithmetic is a kind of SystemException.

Exception = inheriting from a class SystemException Arithmetic is a public-access class.

ArithmeticException is a public class that is inherited by other classes.

Remarks

ArithmeticExceptionis the foundation class for the exceptions listed below: ArithmeticException

  • When the divisor is zero, the DivideByZeroException is raised, and this is the case with integer division. For example, attempting to divide 10 by 0 results in aDivideByZeroExceptionexception
  • A NotFiniteNumberExceptionexception is produced when an operation is performed on or returnsDouble
  • And a DivideByZeroExceptionexception is thrown when attempting to divide 10 by 0. NaN,Double. NegativeInfinity,Double. PositiveInfinity,Single. NaN,Single. NegativeInfinity,Single. PositiveInfinity, and the programming language used does not allow such values
  • OverflowException, which is thrown when the result of an operation is outside the boundaries of the target data type
  • And InfinityException, which is thrown when the result of an operation is greater than infinity. That is, it is either less than or bigger than a number’sMinValueproperty, as appropriate. ABytevalue cannot be assigned more than once, for example, since 400 is larger than 256, which is the upper bound of theBytedata type
  • This results in an OverflowExceptionexception being thrown.

This exception should not be handled or thrown by your code. Instead, you should either handle the error or throw it using one of its derived classes, because it provides a more explicit indication of the nature of the mistake. Refer to theArithmeticExceptionconstructors for a list of the initial property values that are assigned to an instance ofArithmeticException. COR E ARITHMETIC is an HRESULT that has the value 0x80070216 and is used by the ArithmeticException.

Constructors

Data Gets a collection of key/value pairs that provide additional user-defined information about the exception.(Inherited fromException)
HelpLink Gets or sets a link to the help file associated with this exception.(Inherited fromException)

Methods

Equals(Object) Determines whether the specified object is equal to the current object.(Inherited fromObject)
GetBaseException() When overridden in a derived class, returns theExceptionthat is the root cause of one or more subsequent exceptions.(Inherited fromException)
GetHashCode() Serves as the default hash function.(Inherited fromObject)

MemberwiseClone() Creates a shallow copy of the currentObject.(Inherited fromObject)
ToString() Creates and returns a string representation of the current exception.(Inherited fromException)

Events

Applies to

  • This is an error that should not be handled or thrown by your code. You should instead use one of its derived classes to either handle or throw the error, as this provides more detailed information about the mistake. See theArithmeticExceptionconstructors for a list of the initial property values for an instance ofArithmeticException. COR E ARITHMETIC is an HRESULT that has the value 0x80070216, and it is used by the ArithmeticException class.

Java Arithmetic Exception Example

With the help of an example, we will understand how theArithmeticExceptionoccurs in Java applications and how to prevent it from occurring. There is a built-in class called ThisArithmeticException in the java.lang package that handles arithmetic errors. FromJavaDoc- In the case of an unusual arithmetic circumstance, theArithmeticException will be thrown. For example, the integer “divide by zero” will result in an instance of this class being thrown. In some cases, the virtual machine may produce ArithmeticException objects as if suppression had been disabled and/or the stack trace had been rendered unreadable.

When an integer is divided by zero, an ArithmeticException results, as seen in the following example.

publicstaticvoidmain (Stringargs) try println(” ArithmeticException has been caught!

printStackTrace(); e.

err.

ArithmeticException has been thrown!
