The JComponent Class

Except for the top-level containers, all components that begin with J inherit from the JComponent class. They get many features from JComponent, such as the ability to have borders, tool tips, and a configurable look and feel.

  • Tool tips

  • Keyboard-generated actions

  • Application-wide pluggable look and feel

  • Properties

  • Support for layout

  • Support for accessibility

  • Double buffering

  • Methods to increase efficiency
