Java基础：多线程join()方法

join()让当前线程优先执行。

JoinThread.java

public class JoinThread implements Runnable{
    @Override
    public void run() {
        for (int i = 0; i < 100; i++) {
            System.out.println("vip"+i);
        }
    }
}

Test.java

import JavaBase.*;
public class Test  {
    public static void main(String args[]) throws InterruptedException {
        JoinThread joinThread = new JoinThread();
        Thread thread = new Thread(joinThread);
        thread.start();

        for (int i = 0; i < 100; i++) {
            if (i == 80) {
                thread.join(1);
            }
            System.out.println("main" + i);
        }
    }
}

运行结果

 程序执行到thread.join(1);其它程序终止，执行该线程。
