  1. public class Swap_Demo
  2. {
  3.     static String emp1, emp2;
  4.     Swap_Demo()
  5.     {
  6.         emp1 = "this is A";
  7.         emp2 = "this is B";
  8.     }
  9.     void swap(String x,String y)
  10.     {
  11.         String res;
  12.         res = x;
  13.         x = y;
  14.         y = res;

  17.     }
  18.     public static void main(String[] args)
  19.     {
  20.         Swap_Demo obj = new Swap_Demo();
  21.         System.out.println("Before swapping:");
  22.         System.out.println("Employee1:"+emp1);
  23.         System.out.println("Employee2:"+emp2);
  24.         System.out.println("After swapping:");
