Java多线程12-线程强制执行join
12、线程强制执行_join
- Join合并线程,待此线程执行完成后,再执行其他线程,其他线程阻塞
- 可以想象成插队
//测试join方法(vip插队)
public class TestJoin implements Runnable{
@Override
public void run() {
for (int i = 0; i < 100; 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();注意线程启动不能放到这里,不然就和主线程一起被随机执行无法体现插队优势
for (int i = 0; i < 1000; i++) {
if (i==200){
thread.start();
thread.join();
}
System.out.println("main"+i);
}
}
}
