Could anyone be kind enough to elaborate on the concept of Enumeration?
Your help will be greatly appreciated.

When I think of enumeration, I think of traversing the contents of a collection. Enumeration and Iteratation are an abstraction such that you don't have to worry about the collection's underlying structure. For instance, traversing a Vector is easy to manage because it's implemented as a dynamic array and, as such, you can use an index. But, to walk a linked list or a set, things are a bit different...
Using Java's enumeration/iteration abstraction, you can use a common interface to traverse various types of collections.
It is sorta covered in the JavaRanch Style Guide.
