In plain English

JavaGuide is a study and interview-prep guide for Java and backend engineers. The repo's description is in Chinese but the topics are clear: java, jvm, mysql, redis, interview, plus newer entries like agent, mcp and context-engineering. The tagline, translated from the README, is a Java interview and general backend interview guide covering computer fundamentals, databases, distributed systems, high concurrency, system design and AI application development. The README recommends reading it on javaguide.cn for a better experience. It works as a long index of Markdown documents in this repository. The table of contents groups topics into: an AI application development guide with subsections on AI Agent basics, prompt engineering, context engineering, Agent Skills, the MCP protocol and workflow versus graph versus loop, an interview preparation section with a backend interview plan, resume guide and project experience guide, a Java section split into basics, collections, IO, concurrency, JVM and new features from Java 8 through Java 25, with deep dives on generics, reflection, source-code analysis of ArrayList and HashMap, JMM, AQS and garbage collection, and a computer-fundamentals section covering operating systems, Linux, shell and computer networks. A paid companion interview cheat sheet and an AI-powered interview-assistant sample project are also mentioned. You would actually use JavaGuide if you are preparing for a Java backend job interview, brushing up on backend concepts, or learning AI-application topics on top of Java skills. The repo's primary language is listed as Java, the content is Markdown documentation.

Copy-paste prompts

Prompt 1
I'm preparing for a Java back-end interview. Walk me through the key differences between ArrayList and LinkedList from JavaGuide, and when to use each.
Prompt 2
Explain how ConcurrentHashMap works internally and why it's better than synchronized HashMap for high-concurrency scenarios, using JavaGuide's approach.
Prompt 3
What are the main garbage collection algorithms covered in JavaGuide, and how do I choose the right one for my application?
Prompt 4
Show me how to study AI application development with JavaGuide's sections on prompt engineering and agents for Java systems.
Prompt 5
Create a 4-week interview prep schedule using JavaGuide's topics: which chapters should I prioritize for a mid-level back-end role?
