一、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

二、测试
package com.massimo.thread;
public class ThreadJoin 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 {
ThreadJoin threadJoin = new ThreadJoin();
Thread thread = new Thread(threadJoin);
thread.start();
for (int i = 0; i < 1000; i++) {
if (i == 200){
thread.join();
}
System.out.println("main" + i);
}
}
}
