Example Swing widgets in Java. Swing is a GUI widget toolkit for Java. [1] It is part of Oracle's Java Foundation Classes (JFC) – an API for providing a graphical user interface (GUI) for Java programs. Swing was developed to provide a more sophisticated set of GUI components than the earlier Abstract Window Toolkit (AWT).
The Swing Application Framework (JSR 296) is a Java specification for a simple application framework for Swing applications, with a graphical user interface (GUI) in computer software. It defines infrastructure common to most desktop applications, making Swing applications easier to create. It has now been withdrawn. [1]

The Java Foundation Classes are comparable to the Microsoft Foundation Class Library (MFC). JFC is an extension of the original Java Abstract Windowing Toolkit (AWT). Using JFC and Swing, an additional set of program components, a programmer can write programs that are independent of the windowing system within a particular operating system.
For function that manipulate strings, modern object-oriented languages, like C# and Java have immutable strings and return a copy (in newly allocated dynamic memory), while others, like C manipulate the original string unless the programmer copies data to a new string.
