我要设计一个日历控件 用 java开发的我的软件是eclipse我该怎么操作呢 求大神指导
这是我以前制作的日历控件，根据网友的代码改写的，自己用着感觉还行。现在没有时间根据你的条件再改写了，如果你觉得合用，就自己再改吧。

java如何在窗口中显示日历
MainFrame.java是显示日历程序，Clock.java是日历计算程序（可以不要）。
编译后运行MainFrame这个类即可。
swing窗口显示万年历，jdk1.4以上环境编译运行。

怎么用java编写日历动态时钟的界面
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
