启动多线程以及延迟输出内容代码

public class TestThread {

    public static void main(String[] args) throws InterruptedException {
        
        //启动了单线程
        
        //Thread.sleep(100);//休眠,毫秒
        
        /*for(int i = 0; i < 20; i++)
        {
            Thread.sleep(1000);//休眠,毫秒
            System.out.println("i = " + i);
            
        }*/

        ThreadTest tt = new ThreadTest();
        
        tt.setName("zxc");
        
        tt.start();//启动线程
        
        ThreadTest tt1 = new ThreadTest();
        
        tt1.setName("tt1");
