Swing

Swing is a library of GUI controls which improves upon the Abstract Window Toolkit.

AWT uses operating system calls to draw components; Swing draws components using its own methods. This gives developers much greater flexibility in designing the look and feel of their applications, while at the same time ensuring that the applications maintain the same look and feel across different platforms.

Swing provides significantly enhanced functionality, such as actions, tables, trees, images buttons, tabs, toolbars, and sliders.
