---------------------- android培训、java培训、期待与您交流！ ----------------------
看了，张老师讲的交通灯，我有一股想把这个程序从新写一编的冲动，因为我认为学习不能光看，还得亲自动手才行。
设计思想：典型MVC，数据模型加控制器加界面显示。具体情况如下：
数据模型：Light类，他主要是保存灯的各种状态，属性状态如下：
1. 开关，标识灯的亮于灭
2. 颜色，红灯，绿灯，黄灯
3. 位置，东，西，男，北
4. 类型，是控制什么信号的，通行，直行，左转，右转，调头
5. 组，现在国际上一般一个颜色信号用3个灯表示，这三个灯就为一组
6. 生命的开始，标识灯在一个信号周期内打开的起始时间，可以有多个开始时间
7. 生命长度，标识在一个信号周期内打开多长时间，可以有间隔
控制器：Control类，他主要是控制等如何有序的亮灭，以及时间间隔的长短。
显示：MainFrame类，他主要是实时显示交通灯和路面的情况，
下面是核心程序
