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.
On April 2, 1997, Sun Microsystems and Netscape announced their intention to combine IFC with other technologies to form the Java Foundation Classes.
[1] Ultimately, Sun merged the IFC with other technologies under the name "Swing", adding the capability for a pluggable look and feel of the widgets.
Because its technology has been merged to constitute Swing and Java 2D, IFC is now no longer maintained.
