线程强制执行join

线程强制执行 join

Join合并线程，待此线程执行完成后，在执行其他线程，其他线程阻塞

//测试join方法，想象成插队
public class TestJoin implements Runnable{
    @Override
    public void run() {
        for (int i = 0; i < 1000; i++) {
            System.out.println("线程vip来了"+i);
        }
    }

    public static void main(String[] args) throws InterruptedException {
        TestJoin testJoin = new TestJoin();
        Thread thread = new Thread(testJoin);
        thread.start();


        //主线程
        for (int i = 0; i < 1000; i++) {
            if (i == 200){
                thread.join();
            }
            System.out.println("main"+i);
        }
    }

}
