Techopedia Explains Java Foundation Classes

Because of its cross-platform capabilities, written Java applications run on any OS without source code change requirements. However, when writing a GUI-enabled application, developers always face a dilemma: Should the same GUI be provided across all platforms, or should the GUI be consistent with the look and feel of its underlying platform?

With the first option, the look and feel of a button, scroll bar, text box or checkbox are the same, regardless of platform. For example, a word processor application developed in Java looks and feels the same when running on Windows or Linux operating systems. With the second option, the buttons, scroll bars and text boxes, etc., change and adapt to the look and feel of the host OS. In this case, the same word processor application looks and feels like a Windows application when running on Windows, but when running on Linux, it looks and feels like a Linux application.

A key JFC advantage is that its components are pluggable and require fewer lines of code. Additionally, JFC retains Java qualities. Thus, the performance of a GUI created through JFC is predictable. An application that runs seamlessly on one OS runs seamlessly on another OS.
