## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 3050, "days_push": 2265, "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 curated collection of Java core knowledge notes covering Java fundamentals, JVM, concurrency, databases, networking, algorithms, operating systems, design patterns, and framework internals (Spring, MyBatis, Kafka, Redis, etc.). It is a study/interview-preparation resource written primarily in Chinese.

## Use cases
- prepare for a Java backend interview
- review JVM and concurrency concepts
- study MySQL and Redis notes
- learn design patterns and system design
- review data structures and algorithms for interviews
- understand how Spring, Kafka, and Netty work internally

## When to choose
- you are preparing for Java backend interviews
- you want consolidated Chinese-language notes on Java ecosystem topics
- you need a quick refresher on CS fundamentals like networking and OS

## When to avoid
- you need up-to-date content covering recent Java versions
- you want English-language materials
- you need runnable code or exercises rather than notes

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, developer-tools
- domain: tutorials, developer-tools, programming-languages, databases
- platform: jvm
- tags: java-interview, study-notes, jvm, computer-networks, design-patterns, system-design, chinese-language, algorithms
