Learn how to play the Java Battleship game.
The playbook is a collection of code snippets that show common programming patterns in Battleship. You will use these plays often, so they will soon become like second nature to you.
You may will encounter many similar programming tasks in your coursework. Build your own playbook to keep track of your programming tricks!
To view the full list of methods available in Battleship, read the API docs.

if (arena.isInRange(this, target)) {
// I've got you in my sights!
