   public static void main(String[] args) {
      Byte b1 = new Byte("100");
      Byte b2 = new Byte("-100");

      int i1 = b1.hashCode();
      int i2 = b2.hashCode();

      String str1 = "Hashcode of Byte " + b1 + " is " + i1;
      String str2 = "Hashcode of Byte " + b2 + " is " + i2;

      System.out.println( str1 );
      System.out.println( str2 );
