The final adventure

Five missions bring the whole journey together.

Learners choose a hero and world, then use variables, maths, decisions, loops, and objects to complete a guided Java adventure.

Answers are checked locally. JavaStart never executes arbitrary code and the adventure does not bypass lesson progress.

Designed with families in mind

A calmer place to learn.

JavaStart has no advertising, public profiles, messaging, location access, behavioural tracking, or required account. Learning progress stays on the device.
