Practical 21

Aim:- Write a program to implement Custom Exception in java.

JAVA Code :-

import java.lang.*;

class MyException extends Exception

{

            int a;

            MyException(int b)

            {

              a=b;

            }

            public String toString()

        {

                        return "Hello its Custom Exception";

            }

}

class CustomException

{

            static void compute(int a) throws MyException

            {

                if(a>10)

                {

                        throw new MyException(a);

                 }

                        System.out.println("Normal exit");

            }

           

            public static void main(String args[])

            {

                try

                {

                        compute(1);

                        compute(11);

                 }

           

                 catch (MyException e)

                 {

                        System.out.println("Caught: " + e);

                  }

            }

}

Output:-
