Description
Provides the classes necessary to create an applet and the classes an applet
uses to communicate with its applet context.
Contains all of the classes for creating user interfaces and for painting
graphics and images.
Drag and Drop is a direct manipulation gesture found in many Graphical User
Interface systems that provides a mechanism to transfer information between
two entities logically associated with presentation elements in the GUI.
Provides classes and interfaces for a general printing API.
Provides the principal classes and interfaces for the Java Print
Service API.
Provides a set of "lightweight" (all-Java language) components
that, to the maximum degree possible, work the same on all platforms.
