• Drawing applets
  • Maze Maker applet (Assignment)
  • Scribble.java (Scribble applet from Java in a Nutshell) (Run this applet.) Note what happens when you occlude, the unocclude, the window. This is because this applet is unable to repaint its image.

  • Scribble2.java (Run this applet.) Note that in this applet you can occlude, the unocclude, the window and the contents will still appear as you left it. This is because this applet keeps its image in an off-screen buffer.

  • ObjectDraw.java (Run this applet.)
