Divisionizer was a tournament management program that was used on several multiplayer sites. It allowed moderators to create a tournament tree and keep track of the match results if the site did not properly support tournaments on its own. The program also could automatically write the rules and results in the chat, saving a lot of typing for the moderators.
The source code can be used to see what my programming looked like 10 years ago. I removed a few lines but otherwise the code and the style are untouched. This program was just one of many Java programs I wrote at that time but it should be representative of them all. Nowadays my programs are better commented and also the style (e.g. naming) has improved since then.
