JavaGuide is a Chinese-language interview-preparation guide for Java back-end developers. The Chinese description on GitHub explains it as a Java interview and back-end general-purpose interview guide covering computer-science fundamentals, databases, distributed systems, high concurrency, system design, and AI application development. The basic problem it solves is that someone preparing for a back-end engineering job in China needs a single, organized place to study all the topics interviewers commonly ask, and JavaGuide collects that material into one structured set of articles. The repository is essentially a giant table of contents that points to detailed Markdown notes inside the docs folder, also published in a more readable form on the website javaguide.cn. Top-level sections shown in the visible README include AI application development (with subtopics on Agents, prompt engineering, context engineering, MCP, and harness engineering), interview preparation strategy, and a deep Java track covering basics, collections (with source-code analyses for ArrayList, LinkedList, HashMap, ConcurrentHashMap, and others), IO, concurrency (thread pools, JMM, AQS, ThreadLocal, CompletableFuture, atomic classes), JVM (memory areas, garbage collection, class loading), and a per-version overview of new features from Java 8 through Java 25. There are also computer-science fundamentals chapters on operating systems, Linux, shell, and networking. The README links to companion paid editions, an AI interview-assistant project built on Spring Boot 4.0, Java 21, and Spring AI 2.0, and a Discord-style invitation to star the repo. You would use JavaGuide if you read Chinese and you are studying for Java back-end interviews, refreshing fundamentals, or learning AI-related concepts that mid-to-large Chinese tech companies are now testing. The repository is primarily Java content delivered as Markdown documentation. The full README is longer than what was provided.
