Swing is a set of program component s for Java programmers that provide the ability to create graphical user interface ( GUI ) components, such as buttons and scroll bars.

* Swing has a wide range of various components, including buttons,
check boxes, sliders, and list boxes.
1. What are Swing Components

3. 1. Top Level Containers
* Every program with a Swing GUI must contain at least one top-level Swing
container that provides the support that Swing components need to perform
their painting and event handling.
* Swing provides three generally useful top-level container classes:
1. JFrame 2. JDialog 3. JApplet.
* Each JFrame object implements a single main window, and each JDialog
implements a secondary window (a window that's dependent on another
window). Each JApplet object implements an applet's display area within a
browser window.

4. When using these classes, you should keep these facts in
mind:
• To appear onscreen, every GUI component must be part of a
containment hierarchy. Each containment hierarchy has a top-level
container as its root.
• Each top-level container has a content pane that, generally speaking,
contains the visible components in that top-level container's GUI.
• You can optionally add a menu bar to a top-level container. The
menu bar is positioned within the top-level container, but outside
the content pane.

5. Here's a picture of a frame created by an application.
The frame contains a green menu bar (with no menus)
and, in the frame's content pane, a large blank, yellow
label.

8. 1. Typically used to collect Basic Controls (JButton,
JChoiceBox…)
