• 结对编程1---四则运算---GUI


    201421123003 黄建英 201421123004 黄美海

    题目描述:

    我们在个人作业1中,用各种语言实现了一个命令行的四则运算小程序。进一步,本次要求把这个程序做成GUI(可以是Windows PC 上的,也可以是Mac、Linux,web,手机上的),成为一个有基本功能、一定价值的程序。在下面的功能需求中实现两个:
    1.记录用户的对错总数,程序退出再启动的时候,能把以前的对错数量保存并在此基础上增量计算;
    2.有计时功能,能显示用户开始答题后的消耗时间;
    3.界面支持中文简体/中文繁体/英语,用户可以选择一种。
    在软件开发中,我们需要大量使用工具来辅助设计,每个环节大家都要善于学习和使用工具。设计的时候,请使用思维导图设计你的模块之间的关系。

    一、需求分析

    1、用户输入数量可随机产生四则运算式
    2、对用户输入的答案进行正确率分析
    3、GUI界面:a、有计时功能,能显示用户开始答题后的消耗时间 b、界面支持中文简体/中文繁体/英语,用户可以选择一种;

    二、思维导图

    三、关键代码说明

    a计时功能

    小结:

    1、这次结对编程实验是我和黄美海同学一起完成,首先我们一起讨论了总体的需求以及该如何设计实现,然后一致决定采用我上次的实验为基础来实现四则运算的GUI界面,黄美海同学负责代码的复审以及提出我的不足;

    2、以前自己编程事总会有小小的不起眼的小毛病,这次结对编程是两个人一起做,在队友的提醒下,做起实验来格外顺手。但是要在上次实验的基础上增加两个功能并用图形界面实现,着实有点吃力,还好查了资料,顺利解决了。

    汉堡包式评价:

    1. 先来一片面包:我们两人达成结对编程的共识,采用JAVA和GUI实现
    2. 再把肉放上:这次编程过程中,我负责主体编程,但是期间遇到了诸多问题和不足,我们经过讨论、查资料就都顺利解决。
    3. 然后再来一片面包: 两人编程中有领航员和驾驶员关系时确实能使工作更加顺利,这次编程让我们对对方的编程实力有了更深的了解,也发现了自己一些编程习惯不是特别好。
