package day16; public class ThreadTest extends Thread { @Override public void run() { //run方法线程体 for (int i = 1; i <= 6; i++) { System.out.println("run方法线程:" + i); } } public static void main(String[] args) { //创建一个线程 ThreadTest thread1 = new ThreadTest(); //开启线程:start() thread1.start(); //main主线程 for (int i = 1; i <= 30; i++) { System.out.println("主线程:" + i); } } }
运行的结果是并发执行,穿插打印,执行结果如下:
