Café Java

This page contains links to some Java^™ applets that I wrote back in 1997 when I was learning how to program in Java. I hope you like them.

The applet pages contain links to the source code if you're curious. Note that I was new to Java at the time, and no doubt there are some improvements that could be made.

Note: When you select an applet (from the menu below) it will open in a separate window. Close the applet's window when you're done.

Java Applets:

• S-Grapher Lite
  This applet lets you view some preset patterns called s-graphs. What is an s-graph? It's the name I've given to a pattern generated by playing around with some trig functions. These patterns look similar to spirographs, but use a different principle.
  
  
• Palindrome Tester
  This little applet let's you type in a phrase and then analyzes it to see if it is a palindrome.
  
  
• Lotto Numbers Selector
  This applet uses a random number generator to pick numbers for lotto or bingo.
  
  
• Digital Clock
  This applet displays the current time in a digital format. It also displays the current date.
  
  
• SketchPad
  This applet lets you use the mouse to draw simple pictures.
  
  
• S-Grapher INXS
  A variation of S-Grapher Lite.
  
  

 

Applets require a Java-enabled browser

 

In recent times client-side Java has lost ground to Flash/Shockwave. Some of the applets presented here may not even work with current browsers. I have rewritten several of these applets using Flash/Shockwave. Nowadays I do most of my Java programming on server-based applications and web sites.

"The programmer, like the poet, works only slightly removed from pure thought-stuff. He builds his castles in the air, from air, creating by exertion of the imagination."

-- Frederick P. Brooks Jr, The Mythical Man Month (1974)
