Java贪吃蛇游戏源代码

游戏贪吃蛇的JAVA源代码一．文档说明a)本代码主要功能为实现贪吃蛇游戏，GUI界面做到尽量简洁和原游戏相仿。

目前版本包含计分，统计最高分，长度自动缩短计时功能。

b)本代码受计算机系大神指点，经许可后发布如下，向Java_online网致敬c)运行时请把.java文件放入default package 即可运行。

1.2设计任务及具体要求本游戏用户可以自己练习和娱乐。

本游戏需要满足以下几点要求：(1)利用方向键来改变蛇的运行方向。

(2)空格键暂停游戏，并在随机的地方产生食物。

(3)吃到食物就变成新的蛇体，碰到壁或自身则游戏结束，否则正常运行。

(4)用户可以根据需要暂停，以及根据水平选择不同的游戏难度。

要求：明确课程设计的目的，能根据课程设计的要求，查阅相关文献，为完成设计准备必要的知识；提高学生用java语言进行程序设计的能力，初步了解软件开发的一般方法和步骤；提高撰写技术文档的能力。
