用JAVA設(shè)計(jì)游戲：貪吃蛇游戲
用MVC方式實(shí)現(xiàn)的貪吃蛇游戲，共有4個(gè)類。運(yùn)行GreedSnake運(yùn)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。

/*
* 程序名稱：貪食蛇
* 原作者：BigF
* 修改者：algo
* 說(shuō)明：我以前也用C寫(xiě)過(guò)這個(gè)程序，現(xiàn)在看到BigF用Java寫(xiě)的這個(gè)，發(fā)現(xiàn)雖然作者自稱是Java的初學(xué)者，
* 但是明顯編寫(xiě)程序的素養(yǎng)不錯(cuò)，程序結(jié)構(gòu)寫(xiě)得很清晰，有些細(xì)微得地方也寫(xiě)得很簡(jiǎn)潔，一時(shí)興起之
* 下，我認(rèn)真解讀了這個(gè)程序，發(fā)現(xiàn)數(shù)據(jù)和表現(xiàn)分開(kāi)得很好，而我近日正在學(xué)習(xí)MVC設(shè)計(jì)模式，
* 因此嘗試把程序得結(jié)構(gòu)改了一下，用MVC模式來(lái)實(shí)現(xiàn)，對(duì)源程序得改動(dòng)不多。
* 我同時(shí)也為程序增加了一些自己理解得注釋，希望對(duì)大家閱讀有幫助。
