本文深入探讨了Java并发编程中CyclicBarrier的使用方法，通过具体实例展示了如何利用CyclicBarrier来协调多个线程的运行，确保它们在达到某个共同的等待点后继续执行。文章还介绍了CyclicBarrier的工作原理及其在实际场景中的应用。

@Slf4j
public class CyclicBarrierExample {
    private static CyclicBarrier cyclicBarrier = new CyclicBarrier(5);

    public static void main(String[] args) throws InterruptedException {
        ExecutorService excutor = Executors.newCachedThreadPool();
        for (int i=0;i<10;i++){
            Thread.sleep(1000);
            final int threadNum = i;
            excutor.execute(new Runnable() {
                @Override
                public void run() {
                    try {
                        race(threadNum);
                    } catch (Exception e) {
                        log.error("exception: {}",e);
                    }
                }
            });
        }
        excutor.shutdown();
    }

    private static void race(int threadNum)throws Exception{
        Thread.sleep(1000);
        log.info("{} is ready",threadNum);
        cyclicBarrier.await();
        log.info("{} is finish",threadNum);
    }
}
