## Overview

JavaTools is a small Windows batch utility for discovering Java installations and generating version-specific launchers. The user runs `java-init.bat` to initialize PATH, list available launchers, or rebuild them. During a rebuild, it scans documented installation sources, determines versions, keeps the newest installation for each major version, and writes launcher files; users can then invoke those launchers to run Java. The README documents these relationships, but no source excerpts were provided, so implementation details beyond that are omitted.

Main entry points: [`java-init.bat`](https://github.com/umitsamli/java-tools/blob/main/java-init.bat) (Java initializer)
