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");

tt1.start();

}

}

public class ThreadTest extends Thread {

public void run()
{
System.out.println("0.0");

for(int i = 0; i < 20; i++)
{
try {
Thread.sleep(1000);
} catch (Exception e) {

e.printStackTrace();
}//休眠,毫秒

System.out.println(this.getName() + " i = " + i);

}
}
}
