The course

Five programming modules cover Java basics, loops, methods, decisions, and arrays. Git lessons cover saving and sharing changes.

Projects open after their required lessons. Game projects include a code refresher, commands, and a checklist.

Code, run, submit

The editor highlights Java and saves automatically. Game projects include 3D worked examples and replay controls.

In game projects and independent challenges, Run tries three public cases and Submit checks at least twenty. Independent challenges keep hints and autocomplete off.
