18.16 java.awt.Container (JDK 1.0)

This class implements a component that can contain other components. You cannot instantiate Container directly, but must use one of its subclasses, such as Panel, Frame, or Dialog. Once a Container is created, you may set its LayoutManager with setLayout(), add components to it with add(), and remove them with remove(). getComponents() returns an array of the components contained in a Container. locate() determines within which contained component a specified point falls. list() produces helpful debugging output.
