    The methods declared by Enumeration are summarized in the following table:

    boolean hasMoreElements()
    - When implemented, it must return true while there are still more elements to extract, and false when all the elements have to be enumerated.

    Object nextElement()
    - This returns the next object in the enumeration as a generic Object reference.
