Java 多线程学习笔记十四(线程强制执行_join)
内容来自B站【狂神说Java】多线程详解
概念
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
代码演示
package com.example.demo.thread;
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();
for (int i = 0; i < 500; i++) {
if (i == 200) {
thread.join();
}
System.out.println("main-->" + i);
}
}
}
