Java实现LED方式显示时间

[Heavenka]

本人最近做java的课程设计，要求：
编写一个时钟（LED方式）程序，要求：
（1）在屏幕上用文字显示日期（年、月、日、星期）与时间。
（2）时间显示要求能动态显示时、分、秒。
本人只知道用文本方式显示动态时间，希望高手讲解实现方式，我想知道的是实现原理，而不仅仅是程序代码。从网上下载了个电子钟程序，原程序中包含很多16进制数，不知道什么原理实现的。

本人只知道用文本方式显示动态时间

上面的要求就是 文本数据显示 动态刷新吧.没别的吧？

[Heavenka]

编写一个时钟（[color=#FF0000]LED方式）程序，要求：
（1）在屏幕上用文字显示日期（年、月、日、星期）与时间。
（2）时间显示要求能动态显示时、分、秒。[/color]

颜色没弄好 重要的就是LED显示

帖子 发得太快了，我还是顶上去。

需要通过 图形界面画出来了...

用图形界面封装下 1~9 数字吧

[火龙果被占用了]

给你个 JavaScript 版的吧，我原来写的：
