CL0610/Java-concurrency
Java Concurrency
该 Java 并发库提供了一套用于管理多线程执行、同步和内存一致性的工具。它作为一个综合框架，通过无锁原子操作、线程安全集合、任务协调原语和工作线程池来实现并发执行。
该项目包括一个专用的线程同步工具包，具有锁存器（latches）、屏障（barriers）和信号量（semaphores），用于协调并发任务的时序和顺序。它还提供了一套并发集合（映射、队列和列表），无需手动锁定即可实现数据共享，以及一个用于对基本类型和引用进行无锁更新的原子操作框架。
该库涵盖了广泛的功能领域，包括用于优化资源利用的线程池管理、确保数据可见性的内存模型分析，以及防止竞态条件的各种锁管理机制。这些工具共同支持开发在共享内存中保持一致状态转换的多线程应用。
Features
