软件工程——个人项目：五子棋

实验报告

一丶设计摘要：

      通过本次五子棋的设计，实现对本学期内容的回顾与综合运用，包括类的建立，用类创建对象，方法的调用，图形组件的使用方法，图形界面的布局形式，事件处理机制，文件操作的基本方法，数据读写的基本用法、鼠标事件等。

    Java既是一种程序设计语言，也是一个完整的平台。作为一种程序语言，它简洁、面向对象、安全、健壮，以及适用于Internet技术；而作为一个平台（JRE，Java Runtime Environment，Java运行环境或者说是Java虚拟机），对于符合Sun公司Java标准的应用程序，都可以在Java平台上正确运行，与程序运行的操作系统无关。 这个五子棋游戏正是用这个平台做的，在实践中充分体现出了Java面向对象给我们带来的方便。

二丶功能需求：

    本次课程设计实现了五子棋程序的基本玩法，可以扫描棋盘记录连在一起的黑白棋子数，从而判断黑白棋子的胜负。

三丶源代码：

五丶实验心得：

通过此次课程设计，将我本学期所学的java知识得到巩固和应用，在设计的过程中，我遇到了很多问题，不过在老师和同学们的帮助和自己的思考下得到了解决。在这次课程设计中,综合运用了知识，包括类的创建，构造方法和方法等知识。由于自己的分析设计和程序经验不足，该系统设计和实现过程有诸多不足，比如用户界面不够美观等等，这些有待进行进一步完善和提高。对于文中出现的不足和系统出现的问题，敬请老师指导。
