AWT Hierarchy
The Abstract Window Toolkit (AWT) package in Java enables the programming to create GUI-based applications. It contains several classes that help to implement everyday window-based tasks—such as windows, adding a scroll bar, buttons, list items, text boxes, etc.
All the classes are contained in the java.awt package. These classes are hierarchically arranged inside the AWT package. AWT provides support for both standard and applet windows.
