## What it is
The companion repository for the Chinese book 'Pragmatic Java Engineer' (Java工程师修炼之道), which outlines the essential knowledge system for Java backend engineers. It includes an online GitBook, source code examples, and errata covering engineering practices, frameworks, data storage, concurrency, networking, and performance optimization.

## Use cases
- learn java backend engineering best practices
- structure my java knowledge system
- study java concurrency and netty networking
- understand redis distributed locks and kafka semantics
- prepare for senior java engineer interviews
- find a roadmap for java architecture skills

## When to choose
- you are an intermediate Java developer wanting a curated overview of the backend ecosystem
- you prefer concise, notes-style coverage of many Java topics
- you want free online access to the book's content and code examples

## When to avoid
- you are a complete beginner to programming or Java
- you need deep, exhaustive treatment of a single technology
- you need up-to-date coverage of the newest Java versions and frameworks

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, developer-tools
- domain: programming-languages, backend, tutorials, developer-tools, databases, apis
- platform: jvm, cross-platform
- tags: java, book, backend-engineering, architecture, concurrency, distributed-systems, spring, netty, redis, kafka, elasticsearch, performance-tuning, chinese
