Tools: vi & Sun's Java SDK 1.4.1

Q: how do you normally test an applet? Any errors in my code & html?

Mozilla 1.2.1 & the same SDK doesn't run it either. A red cross on the top-left.

You don't have an init() method, so it won't run. Applications need a main() method, Applets need an init() method.

Appletviewer isn't working on my computer either (I've never used it). Buf if I check the applet through my web browser (Galeon), it works fine after you add the init method.

And to think I had to shell out 60 bones for a book half as thick as my PC tower...

Thanks very much!
