This page collects a series of WeChat articles (issues 1‑40) that focus on common Java interview questions and concepts.

Issues 1‑10 include topics such as Redis interview Q&A, the relationship between hashCode() and equals(), methods of Object, distributed locks in Redis, singleton pattern implementations, message‑queue ordering, sharding primary‑key handling, choosing between HashMap and TreeMap, and the lifecycle of Spring beans.

Issues 11‑20 discuss why HashMap is not thread‑safe, Java thread states, serialization basics, when to use ArrayList vs LinkedList, common multithreading interview questions, process vs thread differences, message‑queue benefits, and distributed lock implementations.

Issues 21‑30 cover the implementation principles of HashMap, Java collection framework interview questions, ZooKeeper basics, Dubbo interview topics, object liveness and garbage collection, Java Comparable vs Comparator, and other core Java concepts.

Issues 31‑40 explore thread‑pool internals, MyBatis interview questions, TCP/HTTP interview guide, class loading mechanisms, thread termination, database partitioning strategies, composite index usage, Redis string implementation, and Redis failure patterns such as avalanche, penetration, and breakdown.

The collection serves as a comprehensive reference for developers preparing for Java‑related technical interviews.
