### 多线程

#### CyclicBarrier

构造方法， 参数1：子线程await数，参数2：barrierAction线程

```java
CyclicBarrier cyclicBarrier = new CyclicBarrier(5,new CollectThread());
```

子线程依次执行await后阻塞，到达指定次数后，继续执行，且执行barrierAction线程。

#### CountDownLatch

执行

```java
countDownLatch.countDown();
```

后计数减一，减到0后，countDownLatch.await的地方继续执行。
