  public static void main(String[] args) {
    //creating an empty Enumeration
    Enumeration<Integer> MyEnum = Collections.emptyEnumeration();

    //print the content of the Enumeration
    while(MyEnum.hasMoreElements()) {
      System.out.println(MyEnum.nextElement());
    }
    System.out.println("MyEnum is empty.");
