History

AWT existed before JFC. 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

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. Using the Java programming language, Java Foundation Classes (JFC) are pre-written code in the form of class libraries (coded routines) that give the programmer a comprehensive set of graphical user interface (GUI) routines to use. The Java Foundation Classes are comparable to the
