如何用Java语言写一个贪吃蛇游戏
设计游戏，首先就要设计界面。首先看一下我设计的一个界面。界面分为左边的游戏区与右边的控制区。游戏区包含“得分信息”和贪吃蛇的游戏区，右边控制区有“开始”“暂停”“停止”按钮，等级选择单选框以及游戏排行榜。
所以我们需要定义swing组件，并在类初始化时初始化这些组件，添加组件。因为后面设计游戏的时候，我们要确切知道游戏区的大小，所以这里设置游戏区固定大小值。本来想用布局来更好的管理，但作者对布局也掌握不够，所以就先设置固定大小吧。
定义我们的游戏。贪吃蛇游戏其实就是包含很多细小网格，然后蛇在网格中移动。蛇由一连串的网格组成，为了视觉效果，蛇身用蓝色标记，食物用红色标记，背景白色。如第一张图片所示。所以，我们需要定义二维数组，保存网格信息，保存蛇身和食物的位置信息等。初始化时，还需要添加键盘事件控制上下左右移动。
食物的位置信息是二维的，所以我简单定义了一个类用来保存二维信息。
接着就是实现游戏的功能了。开始，暂停，停止按钮添加事件控制游戏开始。等级按钮定义游戏难度等。
开始游戏后，我们定义一个定时器。蛇身按照指定的方向移动，方向是通过初始化时添加的键盘事件，键盘的上下左右按钮来控制。蛇身是连续的位置信息，保存到队列中，所以蛇身的移动就是队首增加一个位置，队尾减少位置，然后重新绘画游戏区就可以了。
在蛇身移动时进一步做吃掉食物、撞墙、撞到自己的处理。这是游戏的主要逻辑。
最后，游戏结束我们弹出一个对话框提示是否保存游戏得分。我们制作了排行榜信息，只保留前10名的游戏得分。首先定义了一个实现Comparable接口的游戏得分类，按得分高，时间最早来排序。
游戏结束时保存得分信息，看是否进入到排行榜中。而之前在初始化排行榜组件时就会加载游戏排行榜信息。
通过保存和读取排行榜信息，我们也熟悉一下文件读取操作，还有集合、排序算法的功能。

具体的编译和界面还是要靠你。
用JAVA设计游戏：贪吃蛇游戏
用MVC方式实现的贪吃蛇游戏，共有4个类。运行GreedSnake运行即可。主要是观察者模式的使用，我已经添加了很多注释了。

/*
* 程序名称：贪食蛇
* 原作者：BigF
* 修改者：algo
* 说明：我以前也用C写过这个程序，现在看到BigF用Java写的这个，发现虽然作者自称是Java的初学者，
* 但是明显编写程序的素养不错，程序结构写得很清晰，有些细微得地方也写得很简洁，一时兴起之
* 下，我认真解读了这个程序，发现数据和表现分开得很好，而我近日正在学习MVC设计模式，
