What will be the output of the program?

public class Foo {
 Foo() {
  System.out.print("foo");
 }
 class Bar {
  Bar() {
   System.out.print("bat");
  }
  public void go() {
   System.out.print("hi");
  }
 } /* class Bar ends */
 public static void main(String[] args) {
  Foo f = new Foo();
  f.makeBar();
 }
 void makeBar() {
  (new Bar() {}).go();
 }
} /* class Foo ends */

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;
