Aim:- Show the implementation of ‘throw’ keyword.

JAVA Code :-

import java.lang.*;

class ThrowDemo

{

   static void demo()

   {

            try

            {

               throw new NullPointerException("demo");

            }

            catch(NullPointerException e)

            {

                System.out.println("Caught inside demo...");

                throw e;

            }

     }

     public static void main(String[] args)

     {

            try

            {

              demo();

            }

           

            catch(NullPointerException e)

            {

                System.out.println("Recaught...");    

            }

      }

}

Output:-
