Java program examples

• Hello World application. Makes me wonder what the scientific "hello world" application could be. Simple but relevant. Frog pond (alas Jon Claerbout, Ken Lenga, and Bob Clapp)? Convolution? FFT lab (alas Dave Hale)?
• Draw Rectangle is a simple Java application (not an applet).
• Color Panel plots a color panel.
• ColorPan.java implements the color panel above (from David Flanagan`s Java in a Nutshell by O'Reilly).
• Scribble let's you draw a figure with your mouse.
• Scribble.java implements the Scribble applet (from David Flanagan`s Java in a Nutshell by O'Reilly). The applet uses the Java 1.0 event model.
• Calc.java implements a simple 4-function calculator (translated from Practical C++ Programming by Steve Oaline). This thing really needs an applet interface.
• Time management tool (Applet).
