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?

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