Which one should I pick for a new project?

I can only answer questions about h2pl/javatutorial or tencent/tinker.

That said, these two repositories serve very different purposes, so the choice depends entirely on your project needs:

h2pl/javatutorial (README)

• A learning resource and study guide — a curated collection of Java tutorial documents covering fundamentals, collections, networking, and best practices
• Not a library or framework — it's documentation and educational content
• Use this if you're learning Java, preparing for interviews, or need reference documentation
• RepoPilot signals: WAIT — Slowing (last commit 12 months ago), so content may be dated

tencent/tinker (from the code samples)

• An active hotfix/patching framework for Android applications, with DEX utilities and bytecode manipulation tools
• Shipping code — production-grade libraries with Apache 2.0 licensing
• Use this if you're building an Android app that needs dynamic patch capability

If you're starting a new project:

• Pick tencent/tinker only if you need runtime patching for Android
• Use h2pl/javatutorial only as a learning reference alongside your project, not as a dependency

What kind of project are you building? That will clarify the right choice.

• Is this for Android app development or server-side Java?
• Do you need runtime code patching capabilities?
• Are you building a new library or learning Java fundamentals?
