What will be the output of the program?

public class WrapTest  {     public static void main(String [] args)      {         int result = 0;         short s = 42;         Long x = new Long("42");         Long y = new Long(42);         Short z = new Short("42");         Short x2 = new Short(s);         Integer y2 = new Integer("42");         Integer z2 = new Integer(42);          if (x == y) /* Line 13 */             result = 1;         if (x.equals(y) ) /* Line 15 */             result = result + 10;         if (x.equals(z) ) /* Line 17 */             result = result + 100;         if (x.equals(x2) ) /* Line 19 */             result = result + 1000;         if (x.equals(z2) ) /* Line 21 */             result = result + 10000;          System.out.println("result = " + result);     } }
