Not quite sure I understand your question.
The entrySet method creates a Set with all the entries in.
// Is Entry some static variable that adds the elements of set in a Map
No. It is an interface nested inside the Map interface.

Your post would be easier to understand if you wrote the questions outside the code tags.
Why have you not given the Map type parameters? It would be a lot easier to handle a Map<String, Integer>.

Interface can be nested??

By that you mean is-a relationship ,right using extends keyword?

No it's just an interface defined in another interface.

// Edit: Just to clarify. My no is the answer to the question: By that you mean is-a relationship ,right using extends keyword?

Yes. Open the src.zip file in your Java™ installation folder and you can see how it is done

No. Not at all.
