直接上代码

package com.example.demospringboot.concurrent;

import org.junit.Test;

import java.util.concurrent.CountDownLatch;
import java.util.concurrent.TimeUnit;

public class ThreadAndRunnableTest {

    @Test
    public void testThread(){
        new Thread(()->{
            for(int i = 0; i< 100; i++){
                System.out.println(i);
            }
        }).start();

        // 主线程等待子线程执行完毕
        CountDownLatch countDownLatch = new CountDownLatch(1);
        try {
            // 设置超时时间
            countDownLatch.await(1, TimeUnit.SECONDS);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}
