import packages

[gregorio99]

Hi!
In my program, the two first line are:

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

My question is why I must write it like this?
If import java.awt.* - let me get everything from awt so In my opinion I don't need line java.awt.event.*

The wild card, * sign, only allow to import/use the classes in this package visible, not any of the sub-packages.

java.awt.* only imports classes from the java.awt package and not classes from packages under it.
