Difference between paint, paintComponent and paintComponents in Swing

by
  • AWT, override paint().
  • Swing top-level container (e.g.s are JFrame, JWindow, JDialog, JApplet ..), override paint(). But there are a number of good reasons not to paint in a TLC. A subject for a separate question, perhaps.
  • The rest of Swing (any component that derives from JComponent), override paintComponent().
  • Neither override nor explicitly call paintComponents(), leave it to the API to call it when needed.

Be sure to also use @Override notation whenever overriding a method.

Doing so would hint at the problem of trying to override paintComponent(..) in a JFrame (it has no such method), which is quite common to see.
