① java貪吃蛇技術選型怎麼寫的
Java貪吃蛇技術選型一般需要考慮以下幾點：
開發平台：需要選擇適用於Java語言的開發平台，如Eclipse、IntelliJ IDEA等。
編程語言：需要選擇Java語言來開發貪吃蛇游戲。
框架和庫：可以使用Java中的Swing框架和AWT庫來開發圖形界面，並使用Java多線程編程技術來實現游戲的實時動態效果。
演算法和數據結構：可以使用隊列或鏈表等數據結構來存儲貪吃蛇的身體，並使用類似貪心演算法的思想來決定貪吃蛇的下一步移動方向。
編碼風格和規范：需要遵循Java的編碼風格和規范，確保代碼的可讀性和可維護性。
希望以上內容能夠幫助您了解Java貪吃蛇技術選型。如果您有其他問題，歡迎隨時告訴我，我會盡力為您解答。

⑤ 用JAVA設計游戲：貪吃蛇游戲
用MVC方式實現的貪吃蛇游戲，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，現在看到BigF用Java寫的這個，發現雖然作者自稱是Java的初學者，
* 但是明顯編寫程序的素養不錯，程序結構寫得很清晰，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，發現數據和表現分開得很好，而我近日正在學習MVC設計模式，
* 因此嘗試把程序得結構改了一下，用MVC模式來實現，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。
