java编写windows系统的日历和时钟

Question

用java编写windows系统的日历和时钟，可以不要求设置时间，但起码有点像吧，邮箱[email protected]，有点急哦~~12月11号23点之前有效~~
满意一定再加分~~谢了~~
额~~做了一个晚上，做到精神崩溃~~

Answer 1

import java.lang.Carlendar;
import java.util.Date;

class Mytime extends Thread{ //继承 Thread 类，实现多线程

Thread thread = new Thread();
thread.Start();
public void fun()
{
while(true)
{
Date date = new Date();
thread.Sleep(1000); //设置一秒钟提取一次
txtTime.setText(date) //将时间显示到文本框里,还要提取一下，你自己搞了
}
}
}

日历不写了，
这是动态时间，
你有电脑就要自己调试一下，
我敢肯定是这样做的，
我现在忘记了一些，
这样不行你把thread.Start();
放到while里面去，
但是你改一改绝对会成功，
因为我做了
祝你成功

不知道你用的java教程是哪个版本
我现在用的清华大学出版的《java2实用教程》上有这两个例子
可以去网上搜搜
