吃豆人代碼Java,吃豆人代碼編寫

網(wǎng)上下載的JAVA代碼怎么用

根據(jù)你的描述,eat應(yīng)該是一個(gè)工作空間的文件夾(.metadata是工作空間的配置文件),而那個(gè)EAT就是吃豆子的項(xiàng)目,用Eclipse的話,設(shè)置工作空間到????\eat就可以了.

在蒙陰等地區(qū),都構(gòu)建了全面的區(qū)域性戰(zhàn)略布局,加強(qiáng)發(fā)展的系統(tǒng)性、市場(chǎng)前瞻性、產(chǎn)品創(chuàng)新能力,以專注、極致的服務(wù)理念,為客戶提供做網(wǎng)站、成都網(wǎng)站制作 網(wǎng)站設(shè)計(jì)制作定制網(wǎng)站建設(shè),公司網(wǎng)站建設(shè),企業(yè)網(wǎng)站建設(shè),成都品牌網(wǎng)站建設(shè),成都全網(wǎng)營銷推廣,外貿(mào)網(wǎng)站制作,蒙陰網(wǎng)站建設(shè)費(fèi)用合理。

一種是在打開的時(shí)候詢問工作空間路徑,輸入你的eat文件夾的絕對(duì)路徑就可以.

另一種是在Eclipse中,選文件(File) - 切換工作空間(Switch Workspace) 然后輸入eat文件夾的絕對(duì)路徑.

常理來講,這樣就能看到源代碼了,至于運(yùn)行,你需要找到這些源代碼中的main方法,你可以在左側(cè)的"包資源管理器(Package)"中找到EAT項(xiàng)目,在上面點(diǎn)擊鼠標(biāo)右鍵,點(diǎn)擊運(yùn)行方式(Run As), 選擇運(yùn)行的方式,不知道你的程序是Applet, 還是Application, 試一下吧,應(yīng)該就可以運(yùn)行起來了.

求一段JAVA編寫的貪吃蛇小程序源代碼

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。

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(gè)程序,現(xiàn)在看到BigF用Java寫的這個(gè),發(fā)現(xiàn)雖然作者自稱是Java的初學(xué)者,

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