summary

A practical path for beginners: start on dev.java/playground (browser-run, no persistence), then move to a local JDK and editor, use JShell for quick experiments and single-file execution (since Java 11) for simple scripts, then split into multiple sources (multi-file support improved in recent releases) and adopt a build tool when delivering artifacts. Highlights: IO.readLine and NIO2 simplify terminal and file work, records simplify data modeling, JDK 25 finalizes on‑ramp features; dependency management and testing remain the main pain points.
