JavaStart

JavaStart is a friendly introduction to Java programming for children and complete beginners. Learners join Javi on a colourful journey that turns coding ideas into stories, examples and practical activities. LEARN STEP BY STEP Work through 10 guided lessons covering the story of Java, Hello World, variables, Java maths, decisions, loops, arrays, methods and classes, followed by a final coding adventure. PRACTISE WITH INTERACTIVE EXERCISES Each lesson includes clear examples and practical exercises that help learners connect Java code with familiar ideas. Activities provide immediate feedback so learners can build confidence at their own pace. REINFORCE KNOWLEDGE WITH QUIZZES Answer five questions across each main lesson, with 50 questions in total. Learners need four correct answers to unlock the next lesson, can retry without penalties and can restart the current quiz whenever they wish. STORIES, VOICE AND SOUND Visual stories introduce important concepts while Javi's voice and sound effects provide encouraging feedback. Sound preferences are remembered on the device. TRACK THE LEARNING JOURNEY Earn stars, follow lesson progress and continue from where you stopped. The Start Afresh option resets the learning journey and stars after confirmation while preserving sound preferences. DESIGNED FOR PRIVATE, SELF-PACED LEARNING JavaStart does not require an account or developer-operated backend. Learning progress and preferences are stored locally on the device. Core lesson content is available directly in the app. JavaStart gives new learners a playful, structured way to understand the foundations of Java and complete their first coding adventure.
