public class Main

public static void main(String[] args)

int a,b;

System.out.println("Enter the two numbers: ");

Scanner s= new Scanner(System.in);

a = s.nextInt();

b = s.nextInt();

System.out.println("Number before swapping:" +a+" " +b);

a=a+b;

b=a-b;

a=a-b;

System.out.println("Number after swapping:" +a+" " +b);
