❸ 用JAVA设计游戏：贪吃蛇游戏

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。
