The components at the top of any Swing containment hierarchy.
| JApplet | JDialog | JFrame |
|
Intermediate containers that can be used under many different circumstances.
| JPanel | JScrollPane | JSplitPane |
 |
 |
| JTabbedPane | Box | |
 |
Intermediate containers that play specific roles in the UI.
| JInternalFrame | JLayeredPane | JRootPane |
| JToolBar | JDeskTopPane | |
 |
Regular components that exist primarily to get input from the user; they generally also show simple state.
| JButtons | JComboBox | JList |
 |
 |
 |
| JMenu | JSlider | JTextField |
 |
 |
 |
| JCheckBox | ||
Regular components that exist solely to give the user information.
| JLabel | JProgressBar | JToolTip |
