## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 3592, "days_push": 2099, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A collection of Chinese-language reading notes analyzing the JDK source code, covering concurrency utilities, collections, IO/NIO, networking, and reflection. It is a documentation-style learning resource rather than runnable software.

## Use cases
- understand how HashMap and ConcurrentHashMap work internally
- learn JDK thread pool implementation details
- study ReentrantLock and AQS source code
- deep dive into Java NIO and FileChannel internals
- prepare for Java backend interviews on JDK internals

## When to choose
- you want guided notes while reading JDK source code
- you prefer Chinese-language explanations of Java internals
- you need coverage of concurrency, collections, and IO internals in one place

## When to avoid
- you need up-to-date analysis of recent JDK versions (notes date to ~2020)
- you want runnable code or a library to depend on
- you need English-language material

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, developer-tools
- domain: tutorials, developer-tools
- platform: jvm, cross-platform
- tags: jdk, source-code-analysis, notes, java, concurrency, collections, nio
