I'm just curious: if you "don't know", how you came to the idea that you may need such thing as a function returning an iterator. May I assume that this is because someone requested you to create such thing, gave you an assignment?

This is what I would suggest: learn iterators, their purposes, decide what iterators you need and why, practice in using them, and then just create a function (do you need to learn what is "return" and how it's used?) and return what you need.

Please see my comment to the question. This is what I would suggest:

Learn what is Java iterator: Iterator (Java Platform SE 7).
Learn what are the iterators good for:
Java — How to use Iterator?,
Java Practices — Two ways of using Iterator,
How to use Iterator in Java.
Learn what is function/method, function/method parameters, their types and passing them, function return, how all this works. I'm not sure if you need any links. Perhaps… Java — Methods.
Understand what iterators do you need and why.
Write exactly what you need.

Good luck.
