举个例子,五个人开黑,少一个人就开不了。
java
1public static void main(String[] args) throws Throwable {
2 CyclicBarrier cb = new CyclicBarrier(5, new Runnable() {
3 @Override
4 public void run() {
5 System.out.println("人都到齐了,游戏开始进入峡谷");
6 }
7 });
8 Runnable player = new Runnable() {
9 @Override
10 public void run() {
11 System.out.println(Thread.currentThread().getName() + "已经进来了");
12 try {
13 cb.await();
14 } catch (Throwable e) {
15 e.printStackTrace();
16 }
17 }
18 };
19 new Thread(player, "上路程咬金").start();
20 new Thread(player, "中路安琪拉").start();
21 new Thread(player, "下路小鲁班").start();
22 new Thread(player, "辅助李元芳").start();
23 new Thread(player, "打野孙悟空").start();
24 }
