Java JUC并发包之CyclicBarrier循环栅栏

前言CyclicBarrier 字面意思是循环栅栏，是一个同步的工具，能够允许一组线程去互相等待直到都到达了屏障，CyclicBarrier对于涉及到固定大小的线程是非常有用的，线程们必须相互等待。该屏障称之为循环屏障，是因为当等待屏障的线程被释放之后，该屏障能循环使用。什么意思呢？假如有五个探险者...

Java——多线程高并发系列之JUC三大辅助类（CountDownLatch、CyclicBarrier、Semaphore）

写在前面JUC中提供了三种常用的辅助类，通过这些辅助类可以很好的解决线程数量过多时 Lock 锁的频繁操作。这三种辅助类为：· CountDownLatch: 减少计数· ...

【小家java】JUC并发编程工具之CountDownLatch（闭锁）、CyclicBarrier、Semaphore的使用（下）

CyclicBarrier和CountDownLatch的区别 CountDownLatch的计数器只能使用一次。而CyclicBarrier的计数器可以使用reset() 方法重置。所以CyclicBarrier能处理更为复杂的业务场景，比如如果计算发生错误，可以重置计数器，并让线程们重新执行一次...

【小家java】JUC并发编程工具之CountDownLatch（闭锁）、CyclicBarrier、Semaphore的使用（上）

前言这三个类都是JDK5为我们提供的处理并发编程的工具。CountDownLatch：是一个同步工具类，用来协调多个线程之间的同步，或者说起到线程之间的通信（而不是用作互斥的作用）。CyclicBarrier：字面意思是可循环使用（Cyclic）的屏障（Barrier&#...
