Uses of Class
java.awt.Component

Packages that use Component
java.applet	Provides the classes necessary to create an applet and the classes an applet uses to communicate with its applet context.
java.awt	Contains all of the classes for creating user interfaces and for painting graphics and images.
java.awt.event	Provides interfaces and classes for dealing with different types of events fired by AWT components.

Uses of Component in java.applet

Subclasses of Component in java.applet

class Applet
An applet is a small program that is intended not to be run on its own, but rather to be embedded inside another application.
