Q : Why is my java.awt.event.*; import 'unused' yet I use it in my code?

Before you read through, I apologize if this question wastes your time.

It's not necessarily a problem, and my code runs fine in any case, so I don't necessarily need a problem solved. It's just more of a curious question.

In a Java file, I use java.awt.event.ActionListener quite frequently through out the code, yet, I don't have java.awt.event.ActionListener imported, and when I do import it, it tells me the import is unused? Is it that I have it imported in another file that is in the same package? Or is action listener just a generalized import, now? Again. Just curious, no actual problem.

The only way you can avoid to import a class is whenever you have it in the same package as your own or if you are writing the fully qualified name.

if you have 

import java.awt.event.*;
import java.awt.event.ActionListener;

then I believe the specific import is just getting ignored because your code already imported everything from java.awt.event but you'll have to post some code to get a definitive answer. Your question is a little confusing cause you say java.awt.event.* in the title but then java.awt.event.ActionListener in your description

If you write in code full class name like java.awt.event.ActionListener, then no class import required. Try write ActionListener and you'll see, that import is needed.
