Hi,
What is Iterator, Comparator and Enumerator? I am always confused these two things. I really appreciate if someone provide me the coding that explains iterator and comparator and enumerator

Iterators and enumerators have the same job function; to walk through a collection of data objects one element at a time. That's it.
The reason they are described so generally in some documentation is that the interfaces hide the details of how they work. This is intended to keep the use of such objects clear without requring an understanding of the implementation. Unfortunately, it also makes things a bit harder to work out, if you're learning.
Read a tutorial on the Collections API for a full treatment.

In case you need some links, you can find some useful information on the following web pages:
The Java Tutorial (including The Collections Trail)
The Java API documentation
These are both very useful links, so you should bookmark them. I especially encourage you to learn how to navigate the API docs. If you know what documentation is already available and how to use it, you will be able to find the answers to similar questions on your own in the future.
