JavaGuide

A Chinese language interview guide for Java and backend developers, covering computer science basics, databases, distributed systems, concurrency, and system design.

The description calls it a Java interview and general backend interview guide, spanning computer basics, databases, distributed systems, high concurrency, system design, and AI application development. The README opens by pitching a real world project: an AI interview assistant platform plus a RAG knowledge base built on Spring Boot 4.0, Java 21, and Spring AI 2.0, framed as well suited for learning and resume projects with a low entry barrier.

Two paid supplements get their own mentions. The first is a Java interview guide, four years in the making, positioned as complementary to the open source content for preparing systematically from zero. The second is a set of more than 30 high frequency system design and scenario questions, aimed at the current interview trends at mid size and large companies. The README also points newcomers toward a structured plan for passing Java backend interviews.

A separate guide for AI application development is described as open sourced for backend developers. It covers LLM, Agent, RAG, MCP, Claude Code, Codex, and related core technologies and engineering practice, and the README positions it as the AI counterpart to JavaGuide, complete with a request for stars.

One section walks through disaster recovery and geo redundant multi active setups. Backup means keeping multiple copies of all important data. Disaster recovery means building two identical systems in different locations so the whole application can switch over when one site fails. Geo redundant multi active, by contrast, deploys services in multiple locations that all serve traffic at the same time; that is the main difference from traditional disaster recovery. It exists to handle emergencies like fires and earthquakes, natural or man made.

The README carries a reprint policy: articles are original unless marked as reprints, reprints must cite the source, and malicious copying is pursued legally. It ends with a request for a star and notes GitHub and Gitee as the official homes. JavaScript is recorded as the primary language, an oddity given the content, and the license is Apache-2.0.
