WHAT ARE AWT CLASSES IN JAVA

A description of Java's user interface toolkit

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.
