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。

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。
