   import java.util.*;  

   class Swap_With {  

       public static void main(String[] args) {  

          int x, y, t;// x and y are to swap  

          Scanner sc = new Scanner(System.in);  

          System.out.println("Enter the value of X and Y");  

          x = sc.nextInt();  

          y = sc.nextInt();  

          System.out.println("before swapping numbers: "+x +"  "+ y);  

          /*swapping */  

          t = x;  

          x = y;  

          y = t;  

          System.out.println("After swapping: "+x +"   " + y);  

          System.out.println( );
