Robocode — Learn Java by playing

Robocode is an educational
game from IBM that simulates robot battles and helps you explore Java. You could call it
an IDE that lets you build and manage robots of your own, then send them
into tank battles. Don’t worry, it’s made for beginners. Just subclass a robot
of your own and head into battle. Martin Švihla goes into more detail
on root.cz in Robocode — Learn Java by Playing. I can’t wait
to test my first bot tonight.
