AWT CLASSES

The Abstract Window Toolkit(AWT) contains numerous classes and methods that allow you to create and manage windows. Although the main purpose of the AWT is to support applet windows, it can also be used to create stand-alone windows that run in GUI environment, such as windows.

The AWT classes are contained in the 'java.awt' package. Fortunately, because it is logically organized in a top-down, hierarchical fashion, it is easier to understand and use.

Following are the list of some AWT classes.
