修饰实例方法； 6 | 2. 修饰静态类方法； 7 | 3. 修饰代码块。 8 | 9 | > 需要注意如果synchronized锁对象时当前实例对象this，如果调用不同对象的同步方法，不会产生互斥效果 10 | 11 | ##### LagouReentrantLockTest.java 12 | ReentrantLock需要手动加锁和释放锁，因此一般在finally语句块中调用unlock操作，释放锁对象。 13 | 14 | ##### LagouFairLockTest.java 15 | ReentrantLock可以实现公平锁 16 | 17 | ##### ReadWriteTest.java 18 | ReentrantReadWriteLock读写锁可以实现读写操作分离，当读操作时不产生互斥，只有写操作时才会阻塞其它线程的读写操作 19 | --------------------------------------------------------------------------------

-------------------------------------------------------------------------------- /AndroidLessons/lesson_eleven/SourceCode/README.md: -------------------------------------------------------------------------------- 1 | ### 线程池的创建 2 | ##### CreateSingleThreadPool.java 3 | 创建一个单线程化的线程池，它只会用唯一的工作线程来执行任务，保证所有任务按先进先出的顺序执行。 4 | 5 | ##### CreateCachedThreadPool.java 6 | 创建一个可缓存线程池，如果线程池长度超过处理需要，可灵活回收空闲线程，若无可回收，则新建线程。 7 | 8 | ##### CreateFixThreadPool.java 9 | 创建一个固定数目的、可重用的线程池。 10 | 11 | ##### CreateScheduledThreadPool,java 12 | 创建一个定时线程池，支持定时及周期性任务执行。 13 | 14 | ### 线程池流程分析 15 | ##### LessThanCoreCount.java 16 | 当前线程池中运行的线程数量还没有达到 corePoolSize 大小时，线程池会创建一个新线程执行提交的任务，无论之前创建的线程是否处于空闲状态。 17 | 18 | ##### MoreThanCoreCount.java 19 | 当前线程池中运行的线程数量已经达到 corePoolSize 大小时，线程池会把任务加入到等待队列中，直到某一个线程空闲了，线程池会根据我们设置的等待队列规则，从队列中取出一个新的任务执行。 20 | 21 | ##### NoCoreThread.java 22 | 如果线程数大于 corePoolSize 数量但是还没有达到最大线程数 maximumPoolSize，并且等待队列已满，则线程池会创建新的线程来执行任务。 23 | 24 | ##### ThreadPoolRejectHandle.java 25 | 如果提交的任务，无法被核心线程直接执行，又无法加入等待队列，又无法创建“非核心线程”直接执行，线程池将根据拒绝处理器定义的策略处理这个任务。 26 | 27 | ### 线程池造成OOM 28 | ##### FixedThreadPoolOOM.java 29 | 使用无界阻塞队列，当核心线程执行时间很长，则新提交的任务还在不断地插入到阻塞队列中，最终造成OOM。 30 | 31 | ##### CachedThreadPoolOOM.java 32 | 缓存线程池的最大线程数为 Integer 最大值。当核心线程耗时很久，线程池会尝试创建新的线程来执行提交的任务，当内存不足时就会报无法创建线程的错误。 33 | --------------------------------------------------------------------------------
