Phaser提供了动态增parties计数,这点比CyclicBarrier类操作parties更加方便.它是jdk1.7新增的类,今天我们就来学习一下它的用法.尘埃落定之后,回忆别来挑拨. Phaser的简单使用 一.Phaser的arriveAndAwaitAdvance方法使用 package com.linux.thread.thread; import java.util.concurrent.Phaser; public class PhaserRun1 { public stati
相信对于继承和多态的概念性我就不在怎么解释啦!不管你是.Net还是Java面向对象编程都是比不缺少一堂课~~Net如此Java亦也有同样的思想成分包含其中. 继承,多态,封装是Java面向对象的3大特征. 继承 如果用.Net写一个A类继承B类的话,写法会是大致如下: Public Class A : B{ ....... } Java的话却要通过extends关键字在声明类的时候指定其父类(基类),所以上面的.Net写法要转换成Java的话应该是下面的样子: Public clas A ext

arriveAndAwaitAdvance()方法 arriveAndAwaitAdvance()作用是当前线程已经到达屏障,在此等待一段时间,等条件满足后继续向下一个屏障执行. public class PrintTools { public static Phaser phaser; public static void methodA() { System.out.println(Thread.currentThread().getName() + " A1 begin " +
java.util.concurrent包的类都来自于JSR-166:Concurrent Utilities,官方的描述叫做“The JSR proposes a set of medium-level utilities that provide functionality commonly needed in concurrent programs. ”.作者是大名鼎鼎的Doug Lea,这个包的前身可以在这里找到,它最好的文档就是系统的API手册. 当然,这里参考的concurrent包
在Java多线程编程中,经常会需要我们控制并发流程,等其他线程执行完毕,或者分阶段执行.Java在1.5的juc中引入了CountDownLatch和CyclicBarrier,1.7中又引入了Phaser. CountDownLatch A synchronization aid that allows one or more threads to wait until a set of operations being performed in other threads completes
