Write A Java Program To Swap Two Numbers Without Using The Third Variable.

import java.util.Scanner;

class swap TwoNumberWithoutThirdVariable

{

    public static void main(String args[ ])

    {

         int x, y;

         System.out .println("Enter x and y");

         Scanner in = new Scanner(System.in);

         x = in.nextInt( );

         y = in.nextInt( );

         System.out.println("Before swapping\ nx = "+x+"\ ny = "+y);

         x = x + y;

         y = x - y;

         x = x - y; 

        System.out.println("After Swapping Without Third Variable\nx = "+x+"\ny = "+y);

   

      }

}

Output:

Enter x and y

45

98

Before Swapping

x =45

y = 98

After Swapping Without a Third Variable

x = 98

y = 45
