I think that I figured out what is what here.
enum is the new keyword in
5 that allows you to implement enumerated types.
Enum is a class in java.lang for which types defined using the enum keyword all all subclasses.
Enumerator is similiar to an Iterator only the Enumerator is an older class.
Iterator is a newer class than Enumeration that allows you to iterate over objects of classes that implement Iterable.
Then there is the new for-each loop in Java 5 that is an alternative to using an object of type Iterator to iteration over an array or an object that implements the Iterable interface.
Is this all right?

Ask a Meaningful Question
Getting someone to think and try something out is much more useful than just telling them the answer.
I agree. Here's the link:
