Write a program that ask user to enter values in two integer a and b, now write a code to swap the values of a and b without taking any temporary variable.

import java.util.Scanner;

public class Swap

{

public static void main(String[]hjk)

{

int a,b;

Scanner s1=new Scanner(System.in);

System.out.println("enter first num as a");

a=s1.nextInt();

Scanner s2=new Scanner(System.in);

System.out.println("enter second num as b");

b=s2.nextInt();

a=a+b;

b=a-b;

a=a-b;

System.out.println("the swapped num are");

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

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

}

}
