java.lang.ArithmeticException is Unchecked exception and sub class of java.lang.RuntimeException. It’s thrown when an exceptional condition occurred in Arithmetic Operations. It can also occurred by virtual machine as if suppression were disabled and /or the stack trace was not writable.

Constructors:

• ArithmeticException() : Constructs an ArithmeticException with no detail message.
• ArithmeticException(String s) : Constructs an ArithmeticException with the specified detail message.

package example;

public class ArithmaticExceptionExample {

	public static void main(String[] args) {
		int x=0;
		int y=5;
		double z=6;
		float l=6;
		long k=10L;
		//Integer value divide by integer value as 0 throw ArithmeticException
		try
		{
			System.out.println("Integer value divide by zero");
		System.out.println(y/x);
		}
		catch(ArithmeticException ex)
		{
			ex.printStackTrace();
		}
		//Double value divide by integer value as 0 No Exception special value Infinity
		System.out.println("Double value divide by zero");
		System.out.println(z/x);

		//Float value divide by integer value as 0 No Exception special value Infinity
		System.out.println("Float value divide by zero");
		System.out.println(l/x);

		//Long value divide by integer value as 0 throw ArithmeticException
		try
		{
		System.out.println("Long value divide by zero");
		System.out.println(k/x);
		}
		catch(ArithmeticException ex)
		{
			ex.printStackTrace();
		}

	}

}

Output:

Integer value divide by zero
java.lang.ArithmeticException: / by zero
	at example.ArithmaticExceptionExample.main(ArithmaticExceptionExample.java:15)
Double value divide by zero
Infinity
Float value divide by zero
Infinity
Long value divide by zero
java.lang.ArithmeticException: / by zero
	at example.ArithmaticExceptionExample.main(ArithmaticExceptionExample.java:31)

How to fix Arithmetic Exception?

In above example:

Y/X or K/X result ArithmeticException

What happens here is that since both the dividend and the divisor are int, the operation is an integer division, whose result is rounded to an int. Remember that an int can only contain whole number (of limited range, some 4 billion numbers approximately) That’ s why throwing Arithmatic Exception. same case for long value.

Z/X or L/X result special value Infinity

Here float (L) or double (X) precision value  divide by zero store in float and double value that why result is special value Infinity.
