求一段JAVA编写的贪吃蛇小程序源代码

用MVC方式实现的贪吃蛇游戏,共有4个类。运行GreedSnake运行即可。主要是观察者模式的使用,我已经添加了很多注释了。

1、

/*

* 程序名称:贪食蛇

* 原作者:BigF

* 修改者:algo

* 说明:我以前也用C写过这个程序,现在看到BigF用Java写的这个,发现虽然作者自称是Java的初学者,

* 但是明显编写程序的素养不错,程序结构写得很清晰,有些细微得地方也写得很简洁,一时兴起之

* 下,我认真解读了这个程序,发现数据和表现分开得很好,而我近日正在学习MVC设计模式,

* 因此尝试把程序得结构改了一下,用MVC模式来实现,对源程序得改动不多。

* 我同时也为程序增加了一些自己理解得注释,希望对大家阅读有帮助。
