## What it is
A curated Java interview study guide ('Java Interview Cheatsheet') covering Java fundamentals, concurrency, JVM, MySQL, Redis, Spring, MyBatis, Kafka, operating systems, networking, system design, and distributed systems. It is maintained as a collection of Markdown notes with an online reading site and PDF downloads.

## Use cases
- prepare for a Java backend developer interview
- review Java concurrency and JVM interview questions
- study Redis and MySQL interview topics
- learn system design and distributed systems questions for interviews
- find common Spring and Kafka interview questions
- brush up on computer networking and OS fundamentals before interviews

## When to choose
- you are a Java developer preparing for backend interviews at internet companies
- you want concise, topic-organized interview question summaries in Chinese
- you prefer a free, community-maintained study guide with PDF and online reading options

## When to avoid
- you need hands-on coding practice or mock interviews rather than reading material
- you need content in a language other than Chinese
- you need an authoritative, formally reviewed reference rather than personal study notes

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: tutorials, programming-languages, databases, developer-tools
- platform: cli
- tags: interview-preparation, java, cheatsheet, jvm, concurrency, distributed-systems, chinese-language, web-server
