Javapex teaches you Java — from your very first line of code to a deployed, full-stack application — without ever leaving your Mac.
Most courses make you watch videos. Javapex makes you write code. Every lesson runs a real Java compiler and runtime built right into the app, so you write Java, run it, and watch it work — instantly, on your own machine. No setup, no cloud, no accounts.
A COMPLETE PATH — ZERO TO FULL-STACK
Ten carefully sequenced modules take you all the way:
• Foundations — variables, logic, loops, and reading errors
• Objects & Classes — clean, object-oriented design
• Data & Collections — lists, sets, maps, and generics
• Modern Java — lambdas, streams, records, pattern matching
• Tooling & Craft — real Gradle projects and JUnit testing
• Persistence — SQL, JDBC, and the repository pattern
• Spring Boot — the framework behind Java's backend world
• The Web Frontend — server-rendered pages with Thymeleaf and HTMX
• Engineering Maturity — logging, validation, and clean code
• Capstone — build, containerize, and deploy a real app
LEARN BY DOING
• A real compiler and runtime, fully on-device
• Instant, automatic checking on every exercise
