動手用JAVA做個小遊戲--貪喫蛇

轉眼在大學蹲了快三個春秋，在這幾年裏我可謂是經歷過了大學的“風風雨雨”，逃課、泡女、通宵打機......種種的種種！還有一年就畢業了，回首過去，說實在的還真有點後悔，畢竟看到別人被大公司提前錄用而自己還在碌碌無爲在此我想給那些剛進大學的朋友一個忠告：大學真的真的不是給你來玩的，高中老師說的話都是騙你的，真正能學到的生存技能都在大學裏面獲得的，大學這幾年並沒有你想像的那麼長，稍縱即逝的，好好珍惜吧！

好吧，嘮叨就發到這，下面進入主題：

之所以用JAVA來寫是因爲JAVA是一門典型的面嚮對象語言並且其能跨平臺執行這點對遊戲來說是最大的優勢。（其實最主要的原因是我準備期末考試了，想溫習一下）。

下面我們就開始吧！

首先來創建一個環境窗口即給貪喫蛇活動的院子：
