多线程详解p13、join线程强制执行

package Thread;
public class TestJoin implements Runnable{
    @Override
    public void run() {
        for (int i = 0; i < 200; i++) {
            System.out.println("我是vip"+i);
        }
    }
    public static void main(String[] args) {
        TestJoin tj = new TestJoin();
        Thread th  =  new Thread(tj);
        th.start();
        for (int i = 0; i < 1000; i++) {
            if(i==200){
                try {
                    th.join();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            System.out.println("我没有vip"+i);
        }
