== Special purpose packages ==

=== java.applet===

 

Created to support [[Java applet]] creation, the {{Javadoc:SE|package=java.applet|java/applet}} package allows applications to be downloaded over a network and run within a guarded sandbox. Security restrictions are easily imposed on the sandbox. A developer, for example, may apply a [[digital signature]] to an applet, thereby labeling it as safe. Doing so allows the user to grant the applet permission to perform restricted operations (such as accessing the local hard drive), and removes some or all of the sandbox restrictions. Digital certificates are issued by [[certificate authority|certificate authorities]].

 

=== java.beans ===

 

Included in the {{Javadoc:SE|package=java.beans|java/beans}} package are various classes for developing and manipulating beans, reusable components defined by the [[JavaBeans|JavaBeans architecture]]. The architecture provides mechanisms for manipulating properties of components and firing events when those properties change.

 

=== java.awt ===

 

The {{Javadoc:SE|package=java.awt|java/awt}}, or Abstract Window Toolkit, provides access to a basic set of [[GUI]] widgets based on the underlying native platform's widget set, the core of the GUI event subsystem, and the interface between the native windowing system and the Java application. It also provides several basic [[layout manager]]s, a datatransfer package for use with the [[Clipboard (software)|Clipboard]] and [[Drag and drop|Drag and Drop]], the interface to [[input device]]s such as [[Mouse (computing)|mice]] and [[Keyboard (computing)|keyboards]], as well as access to the [[system tray]] on supporting systems. This package, along with <code>javax.swing</code> contains the largest number of enums (7 in all) in JDK 6.

 

=== javax.rmi ===

The {{Javadoc:SE|package=javax.rmi|javax/rmi}} package provides the support for the remote communication between applications, using the RMI over IIOP protocol. This protocol combines RMI and CORBA features.

 

 

=== javax.swing ===

[[Swing (Java)|Swing]] is a collection of routines that build on <code>java.awt</code> to provide a platform independent [[widget toolkit]]. {{Javadoc:SE|package=javax.swing|javax/swing}} uses the 2D drawing routines to render the user interface components instead of relying on the underlying native [[operating system]] GUI support.
