?pwd=xxn5 提取码: xxn5简介：全书共10章。第1章讲解了线程间的同步性，以及线程间的传输数据控制，即Semaphore和Exchanger类的使用。第2章介绍了在同步处理上更加灵活的工具类CountDownLatch和CyclicBarrier，详细到每个类的API的具体使用与应用场景。第3章是第2章的升级，由于CountDownLatch和CyclicBarrier类都有相应的弊端，所以在JDK 1.7中新增加了Phaser类来解决这些缺点，该类是熟练掌握JDK并发包的必要知识点。第4章是读者应重点掌握的Executor接口与ThreadPoolExecutor线程池，能有效地提高程序运行效率，更好地统筹线程执行的相关任务。第5章讲解Future和Callable的使用，解决线程需要返回值的情况。第6章介绍Java并发包中的CompletionService的使用，因为可以以异步的方式获得任务执行的结果，所以该接口可以增强程序运行效率。第7章介绍接口ExecutorService，该接口提供了若干工具方法来方便执行并发业务。第8章主要介绍ScheduledExecutorService的使用，以掌握如何将计划任务与线程池结合使用。第9章主要介绍Fork-Join分治编程，以提升多核CPU的优势，加快程序运行效率。第10章主要介绍并发集合框架，利用好并发框架，事半功倍。
