CountDownLatch ， CyclicBarrier 与 Phaser并发班 es？
这些类充当同步器。它们如何彼此不同？

What is the difference between CountDownLatch, CyclicBarrier and Phaser Concurrent classes ? These classes works as a synchronizer. How they are different from each other?

推荐答案

CyclicBarrier可以通过调用reset（）方法来重置Barrier到其初始状态。而CountDownLatch不能。 CountDownLatch对于诸如应用程序启动时间的一次性事件是有利的，并且循环障碍可以用于在循环事件的情况下。同时计算大问题等的解。

CyclicBarrier can be used by calling reset() method which resets Barrier to its initial State. Whereas CountDownLatch cannot. CountDownLatch is good for one time event like application start-up time and CyclicBarrier can be used to in case of recurrent event e.g. concurrently calculating solution of big problem etc. Reference: http://javarevisited.blogspot.in/2012/07/countdownlatch-example-in-java.html

对于Phasers，请参考： http://docs.oracle.com/javase/7/ docs / api / java / util / concurrent / Phaser.html

For Phasers refer to this: http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/Phaser.html
