Java Foundation Classes

The Java Foundation Classes (JFC) are a graphical framework for building portable Java-based graphical user interfaces (GUIs). JFC consists of the Abstract Window Toolkit (AWT), Swing and Java 2D. Together, they provide a consistent user interface for Java programs, regardless whether the underlying user interface system is Windows, Mac OS X or Linux.

History

AWT was heavily criticized for being little more than a wrapper around the native graphical capabilities of the host platform. That meant that the standard widgets in the AWT relied on those capabilities of the native widgets, requiring the developer to also be aware of the differences between host platforms.

An alternative graphics library called the Internet Foundation Classes was developed in more platform-independent code by Netscape.

At the same time, another graphics library, called Application Foundation Classes (AFC), was developed independently by Microsoft. It was made to be easier to extend the graphic components, but was primarily aimed for use with the Microsoft Java Virtual Machine.

Ultimately, Sun merged the IFC with other technologies under the name "Swing", adding the capability for a pluggable look and feel of the widgets. This allowed Swing programs to maintain a platform-independent code base, but mimic the look of a native application. The release of JFC made IFC obsolete, and dropped interest for Microsoft's AFC.
