At that time, Netscape developed a GUI library called Internet Foundation Classes (IFC) and Microsoft created Application Foundation Classes (AFC) for GUI development too. So, when Sun Microsystems and Netscape decided to form a new GUI library, they inherited the word Foundation and created JFC. The framework Swing took over the Java GUI programming from AWT and was successfully used for almost two decades...
