THANK YOU

Answer 2

This actually was in my exam, here it is:

package com.company;

/* 11. b) Write a program to input two unequal numbers. Display the numbers after swapping their values in  the variables without using a third variable.

Sample Input: a=23, b=56

Sample Output: a=56, b=23

*/

import java.util.Scanner;

public class Answer11b {

   public static void main(String[] args) {

       Scanner sc = new Scanner (System.in);

       System.out.println("Enter Number a:");

       int a = sc.nextInt();

       System.out.println("Enter Number b:");

       int b = sc.nextInt();

       if (a!=b){

           a = a+b;

           b = a-b;

           a = a-b;

       }

       System.out.println("a = "+a+"    b = "+b);

   }

}
