countDownLatch和cyclicbarrier的区别

countDownLatch和cyclicbarrier的区别，请看下面的代码及注释

public void concurent() throws InterruptedException {
		System.out.println("主线程执行开始");
		CountDownLatch cdl=new CountDownLatch(5);
		CyclicBarrier cyclicBarrier=new CyclicBarrier(5);
		ExecutorService es= Executors.newFixedThreadPool(5);
		for(int i=0;i<5;i++){
			es.execute(()->{
				try{
					System.out.println("子线程："+Thread.currentThread().getName()+"执行");
					//等待5个线程一起执行，进行加操作，满足5个一起执行，执行之后从0开始重新计数
					cyclicBarrier.await();
				}catch (Exception e){
					e.printStackTrace();
				}finally {
					//进行减操作
					cdl.countDown();
				}
			});
		}
		//进行线程等待，减到0的时候，进行释放
		cdl.wait();
		System.out.println("主线程执行结束");
	}
