今天为大家分享一个java语言编写的贪吃蛇系统，目前系统功能已经很全面，后续会进一步完善。整个系统界面漂亮，有完整得源码，希望大家可以喜欢。喜欢的帮忙点赞和关注。一起编程、一起进步
开发环境
开发语言为Java，开发环境Eclipse或者IDEA都可以，数据为SQL SERVER。运行主程序，或者执行打开JAR文件即可以运行本程序。
系统框架
利用JDK自带的SWING框架开发，下载。纯窗体模式，直接运行Main文件即可以。同时带有详细得设计文档。
系统主要功能
性能需求
系统结构化程序设计是讲一个完整的大的系统划分成若干个合适的小的功能，每个具体的功能模块相对独立，系统设计需要遵循以下一些原则。
- 系统性。从整个系统的角度进行考虑，系统的代码要统一，设计规范要标准，传递语言要尽可能一致，对系统的数据采集要做到数出一处、全局共享，使一次输入得到多次利用。
- 灵活性
系统应具有较好的开放性和结构的可变性，采用模块化结构，提高各模块的独立性，尽可能减少模块间的数据偶合，使各子系统间的数据依赖减至最低限度
- 可靠性
可靠性是指系统抵御外界干扰的能力及受外界干扰时的恢复能力。一个成功的管理信息系统必须具有较高的可靠性，如安全保密性、检错及纠错能力、抗病毒能力等。
4 经济性
经济性指在满足系统需求的前提下，尽可能减小系统的开销。一方面，在硬件投资上不能盲目追求技术上的先进，而应以满足应用需要为前提；另一方面，系统设计中应尽量避免不必要的复杂化，各模块应尽量简洁，以便缩短处理流程、减少处理费用
程序启动
1 下载程序源码，解压后导入到ECLIPSE或者IDEA。导入相关的JAR，然后运行Main.java文
件，然后程序进入到系统登陆界面
2 导入数据库文件到SQL SERVER数据库中
主要模块
经过项目小组的调研和讨论，系统分为两个主要模块，普通用户模块和系统管理员模块。普通用的主要的功能是：
- 注册
- 登录
- 管理自己的通讯录
- 管理自己的备忘录
管理员的主要的功能是
- 用户管理。用户的新增，删除，修改。
- 分类管理。分类的新增，删除，修改。
- 备忘录管理。分类的新增，删除，修改。
