The Abstract Window Toolkit (AWT) is Java's original platform-dependent windowing, graphics, and user-interface widget toolkit, preceding Swing. The AWT is part of the Java Foundation Classes (JFC) — the standard API for providing a graphical user interface (GUI) for a Java program. AWT is also the GUI toolkit for a number of Java ME profiles.
AWT and Swing class hierarchy Since early versions of Java, a portion of the Abstract Window Toolkit (AWT) has provided platform-independent APIs for user interface components. In AWT, each component is rendered and controlled by a native peer component specific to the underlying windowing system.
The Java Foundation Classes are comparable to the Microsoft Foundation Class Library (MFC). JFC is an extension of the original Java Abstract Windowing Toolkit (AWT). Using JFC and Swing, an additional set of program components, a programmer can write programs that are independent of the windowing system within a particular operating system.
java.awt: Basic hierarchy of packages for native GUI components java.text: Provides classes and interfaces for handling text, dates, numbers, and messages in a manner independent of natural languages. java.rmi: Provides the RMI package. java.time: The main API for dates, times, instants, and durations. java.beans
The Internet Foundation Classes (IFC) is a GUI widget toolkit and graphics library for Java originally developed by Netcode Corporation and first released by Netscape Corporation on December 16, 1996. The Java IFC was fairly close to the early versions of the Objective-C NeXTStep classes for NeXT.
The AWT Native Interface is designed to give developers access to an AWT Canvas for direct drawing with native code. In fact, the Java 3D API extension to the standard Java SE JDK relies heavily on the AWT Native Interface to render 3D objects in Java. The AWT Native Interface is very similar to the JNI, and the steps are the same as those of ...
The event dispatching thread (EDT) is a background thread used in Java to process events from the Abstract Window Toolkit (AWT) graphical user interface event queue. It is an example of the generic concept of event-driven programming, that is popular in many other contexts than Java, for example, web browsers, or web servers.
The Java 2D API and its documentation are available for download as a part of JDK 6. Java 2D API classes are organised into the following packages in JDK 6: java.awt The main package for the Java Abstract Window Toolkit. java.awt.geom The Java standard library of two dimensional geometric shapes such as lines, ellipses, and quadrilaterals.
