实现了这些接口的有ArrayBlockingQueue, DelayQueue, LinkedBlockingDeque, LinkedBlockingQueue, PriorityBlockingQueue, SynchronousQueue。分别对应于之前几乎所有的容器类。 BlockingDeQueue使用了更先进的“Working-Stell”模型,当一个线程没有工作可以做的时候
关闭Channel会抛出AsynchronousCloseException。多数Channel都实现了InterruptibleChannel。 java.nio的异步非阻塞I/O:如果被阻塞在Selector.select上,可以调用wakeup让它直接返回。 public class ReaderThread extends Thread { private final Socket socket; private final InputStream in; public ReaderThread(Socket socket) ...

不可变对象与初始化安全性:Java 内存模型为不可变对象(同时满足:状态不可修改、所有域都是 final 类型、正确的构造过程)的共享提供了特殊的初始化安全性保证。 任何线程都可以不需要额外同步情况下安全访问不可变对象,即使在发布这些对象时没有使用同步。(final 也是如此,但是,如果 final 类型指向的域是可变对象,那么...

JavaConcurrencyInPractice-任务执行 1、任务 什么是任务? 任务通常是一组抽象且离散的工作单元,通过把程序的功能分解到多个任务, 可以简化程序结构,优化错误处理,以及提供自然的并行工作结构。 找出任务的边界: 在理想的情况下,任务应该是相互独立的,任务的独立有助于实现并发。
