java贪吃蛇求高手现编一个JAVA贪食蛇！

怎么用Java做贪吃蛇的游戏软件呢？

您好，原理: 把蛇身体的每一块看成一个对象（对象存储该块的坐标和相关信息），作为节点存储在线性链表中，再设置一个变量标志蛇的方向（通过按键可以改变）。

一般人都是让每一个节点等于他指向的下一个节点，并让头节点改变位置来实现转弯和移动，这个算法复杂度太高（O(n))，实际上只要做两步操作，插入一个头节点，删除一个尾节点就可以了，新插入的头节点位置根据蛇当前的方向决定 用一个数组将蛇头的行径记录下来，然后第二段的下一个方格设置为蛇头走过的方格，这样子蛇走过的路径都是前一段走过的，最后将跟着蛇头走了，比如 蛇身的路径 for(int i=snakeLength-1;i>0;i--){ rows[i]=rows[i-1];//依次将蛇前面一段走过行的路段赋值给蛇的下一段 cols[i]=cols[i-1];//依次将蛇前面一段走过列的路段赋值给蛇的下一段 } for(int i=1;i<snakeLength;i++){ gamePanel[rows[i]][cols[i]].setBackground(Color.red);//将整个面板上蛇身走过的行和列设置为不同的颜色，当然可以用图片来设置 } 蛇头走过的行和列（rows[0],cols[i]）要根据不同的方向加减1来将面板设置成不同的颜色 如gamePanel[rows[i]－1][cols[i]＋1].setBackground(Color.red)

我想求一个Java编写的贪吃蛇游戏，要有注释和流程图最好

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。

1、 /* * 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， * 因此尝试把程序得结构改了一下，用MVC模式来实现，对源程序得改动不多。

* 我同时也为程序增加了一些自己理解得注释，希望对大家阅读有帮助。

本人用java写贪吃蛇。。。如何实现蛇的自动移动，老师说是线程，但是我的java不太好，希望能说详细点

new Thread(new Runnable() { public synchronized void run() { while(true){ // 写你的每次移动方向和距离算法 try{ // 死循环内 没隔100毫秒运行一次。

Thread.sleep(100); }catch(Exception e){} } } }).start(); 在注释里写你的算法就行了
