Swing (Java GUI Toolkit)

Swing is a Java-based technology used to create graphical user interfaces (GUIs) for applications. It allows developers to design interactive windows, buttons, and other components that users can see and interact with. Swing provides a more flexible and powerful way to build user interfaces compared to older methods, enabling features like custom graphics and advanced layouts. It is part of the Java Foundation Classes (JFC) and is known for its portability, meaning applications built with Swing can run on any device with a Java runtime environment. This makes it a popular choice for desktop applications in Java.
