//测试join方法 //想象为插队 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 < 500; i++) { if (i==200){ thread.join();//插队 } System.out.println("main"+i); } } }
