Java import confusion

Question

What is the difference between:

java.awt.*;

and:

java.awt.event.*;

I find both in many programs.

Answer 1

Like many have said before.

import java.awt.* won't import any classes in java.awt.event...

And the difference between those two package is that java.awt.* include classes like a Frame, Button, etc and the java.awt.event.* package include all event / listener that can happen.

Example, to create a Button you need the class java.awt.Button but if you want that any action happen when you click the Button, you need a java.awt.event.ActionListener that will "wait" for the click, then produce a java.awt.event.ActionEvent.
