JDK5.0新特性系列-11.6线程 BlockingQueue

它们背后所用的数据结构不一样,导致LinkedBlockingQueue的数据吞吐量要大于ArrayBlockingQueue,但在线程数量很大时其性能的可预见性低于ArrayBlockingQueue.*/public class BlockingQueueTest {/*定义装苹果的篮子*/public static class ...

JDK5.0新特性系列-11.1线程 Callable和Future

从本节开始,主要介绍J2SE5.0与线程相关的新特性,新的线程类主要集中在java.util.concurrent 包中,本节实例将介绍如何使用java.util.concurrent.Callable和java.util.concurrent.Future类,用Callable定义一个任务并启动它,然后用它的Future...
