## 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": 2227, "days_push": 1286, "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 free Chinese-language PDF book (5 chapters, 29 sections, ~417 pages) covering Java interview topics including data structures, algorithms, concurrency, JVM, and resume/interview advice, with accompanying source code examples. It is a learning resource rather than runnable software.

## Use cases
- prepare for Java backend interviews at big tech companies
- understand HashMap internals and hash functions
- learn data structures like red-black trees and 2-3 trees with Java examples
- study Java concurrency and JVM fundamentals
- get guidance on writing a resume and interviewing
- deepen understanding of Java core API source code

## When to choose
- you are a Java developer with 1-3 years of experience preparing for interviews
- you want theory paired with runnable Java source code experiments
- you prefer a structured book format covering data structures, algorithms, JVM, and concurrency in one place

## When to avoid
- you need a runnable library or tool rather than educational material
- you cannot read Chinese
- you need up-to-date coverage of the latest Java versions or interview trends

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, documentation
- domain: education, programming-languages, tutorials
- platform: jvm
- tags: interview-preparation, java, ebook, data-structures, jvm, concurrency, career, algorithms
