Swing is a Java-designed GUI toolkit

Swing is a GUI toolkit designed for Java.

Swing is part of the Java Foundation Class.

Swing includes graphical user interface (GUI) devices such as text boxes, buttons, splitter panes, and tables.

Swing offers many better screen display elements than AWT. They are written in plain Java, so they can run across platforms as well as Java itself, unlike AWT.

They are part of the JFC.

They support replaceable panels and themes (specific themes that are the default for various operating systems), but instead of actually using the devices provided by the native platform, they mimic them only on the surface.

This means that you can use any panel supported by Java on any platform.

The disadvantage of lightweight components is that execution is slow, and the advantage is that uniform behavior can be applied across all platforms.
