How many classes are there in AWT?

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 other AWT classes are derived from it.

The AWT provides nine basic non-container component classes from which a user interface may be constructed. (Of course, new component classes may be derived from any of these or from class Component itself.) These nine classes are class Button, Canvas, Checkbox, Choice, Label, List, Scrollbar, TextArea, and TextField.

MenuComponent is an abstract class and is the superclass for all menu-related components.
