求一段JAVA編寫的貪吃蛇小程序源代碼

用MVC方式實現(xiàn)的貪吃蛇游戲，共有4個類。運行GreedSnake運行即可。主要是觀察者模式的使用，我已經(jīng)添加了很多注釋了。

1、

/*

* 程序名稱：貪食蛇

* 原作者：BigF

* 修改者：algo

* 說明：我以前也用C寫過這個程序，現(xiàn)在看到BigF用Java寫的這個，發(fā)現(xiàn)雖然作者自稱是Java的初學(xué)者，

* 但是明顯編寫程序的素養(yǎng)不錯，程序結(jié)構(gòu)寫得很清晰，有些細微得地方也寫得很簡潔，一時興起之

* 下，我認真解讀了這個程序，發(fā)現(xiàn)數(shù)據(jù)和表現(xiàn)分開得很好，而我近日正在學(xué)習(xí)MVC設(shè)計模式，

* 因此嘗試把程序得結(jié)構(gòu)改了一下，用MVC模式來實現(xiàn)，對源程序得改動不多。

* 我同時也為程序增加了一些自己理解得注釋，希望對大家閱讀有幫助。
