Java Programming lab for extra credit (ca 2001)

A snapshot of my extra-credit assignment for my Java programming course at KTH, ca 2001. This is a snapshot from before Git was even invented, and before I learned anything about version control. So it contains the compiled class files as well as the Javadocs, even if these are technically generatable from the source.

Unfortunately, this is an applet which are not supported after Java 9, so it is hard to see it in action.
