The Java AWT (Abstract Windowing Toolkit) contains the
fundamental classes used for
constructing GUIs.
The abstract Component class is the base class for the AWT.
Many AWT classes are derived from it.
These are the old AWT components that are no longer in use.
Some of the AWT classes derived from Component
are Button, Canvas, and Container.
The diagram shows how the classes of the AWT and Swing fit together. Look it over to get an overview. Refer back to it occasionally as you read these notes.
The JComponent class
is derived from Container
and is one of the base classes of Swing.
The JFrame class
is derived from the AWT Frame class.
It is usually the main container for a GUI application.
The JApplet class is derived from the AWT Applet class
and is used for modern applets.
