『Java八股文』Java面试套路，Java进阶学习，打破内卷拿大厂Offer，升职加薪！
A Chinese-language Java interview prep collection — what the Chinese dev community calls '八股文' (eight-legged essay), the rote question-and-answer format that dominates big-tech interviews at Alibaba, ByteDance, Baidu, etc. Covers JUC concurrency, Redis, Kafka, distributed systems, and Java 8 features through long-form Markdown articles. Aimed squarely at Chinese developers grinding for FAANG-equivalent offers.
The concurrency series is genuinely solid — CAS internals, JMM, lock taxonomy, and CountDownLatch are covered with diagrams rather than hand-waving. The Redis section goes beyond surface-level: cache avalanche post-mortems, distributed lock failure stories, and the read-through vs write-through ordering debate are the kind of material that actually shows up in system design rounds. Articles are written from practical war stories (real incidents, real company experience), not just reworded docs. The Kafka piece on why it hits million-TPS is one of the better short explanations of page cache + sequential I/O + zero-copy in Chinese.
Last commit was November 2023 and several series are explicitly unfinished — Semaphore, CyclicBarrier, and Exchanger articles are listed but missing. The whole thing is a personal blog republished as a repo, with heavy WeChat public account promotion baked in; half the links go to WeChat articles behind a login wall, not to the repo itself. No code samples — it's all prose and diagrams, so you can't run or verify anything. Spring content is missing entirely despite being listed as a topic tag.
