Java can surprise you

I thought I knew Java, I'd written code in it for a few years now, but I was wrong. While I was able to solve a problem in Java, I didn't really understand it, I had just developed enough mental workarounds to make it appear so.

With this little project, I'll try to remedy this a bit. I have to write more Java now, and I'd like to be able to say "I know Java" with confidence.

Recently, I came across an interesting idea: to start playing with a language using unit tests, so as to test your understanding of the language and practicing testing at the same time. So I'll try this style of playing on for size.

Open questions

• output arguments
• string immutability
• copying/passing objects and primitives (when is it a copy, when a reference)
