The highest level class in the hierarchy is named Component. The Java
Component class defines objects that can be displayed on the screen and
interact with the user. The notion of a component is similar to that of a
Windows control. Examples of components are buttons, checkboxes,
scrollbars, and menus. The graphical user interface is implemented by
means of components. The Component class is one of the richest in the
AWT. You should consult the Java documentation to inspect the methods
in this class.
