需求分析:
不知道大家是否尝试过这样一种开发模式:你有一个伙伴,你们坐在一起,并肩作战,面对着同一台显示器,使用着同一键盘,同一个鼠标,你们一起思考,一起分析,一起编程?这次,就让我们来体验一下结对编程的魅力:
http://www.cnblogs.com/xinz/archive/2011/08/07/2130332.html
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:
- 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。
- 有计时功能,能显示用户开始答题后的消耗时间。
- 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,参考这位同学的思维导图:

程序设计:
- 一个小组中的两个同学选取比较优秀的 作业1 (两个人的都独立完成了), 把它作为本次作业的基础,然后再修改。
- 结对编程实现上述功能,同样的,在程序正式开发之前,请先预估下PSP每个环节的消耗时间,并在过程中统计实际耗时,最后提交PSP表格。依然注意,这个主要是给你们自己看的,不必造假数据。
-
在两人合作的过程中, 请看下面的内容
a. 满足代码风格规范和代码设计规范(参考书第4章4.1-4.3内容)http://www.cnblogs.com/xinz/archive/2011/11/20/2255971.html
b. 给人提意见的方式——送一个汉堡包http://www.cnblogs.com/xinz/archive/2011/08/22/2148776.html
- 请重视这点,在开发时两个人要有口头上的沟通:“好的,我们一起在开发中遵守一起认可的编码规范”
- 请把你们约定的编码规范文档也提交到gitc. 理解领航员和驾驶员两种角色关系,并在结对编程中两个人轮流做对方的角色。两人都必须参与本次作业的编码工作,并在git提交日志上体现这点。
代码展示:
static randomTest produce= new randomTest(); Vector answer = new Vector(); Vector expression=new Vector(); Vector result=new Vector(); int x=0; int time =0; Endjframe submit=new Endjframe(); public GUI() { initComponents(); } public void produceExpression() { produce.randTest(); expression.add(produce.Expression); result.add(produce.calc); } public void judge() { for(int i=0;i<Integer.parseInt(jTextField1.getText());i++) { if(answer.get(i).equals(result.get(i))) x++; } } public void MyTask() { time++; jLabel3.setText(Integer.toString(time%3600)); jLabel4.setText(Integer.toString(time%60)); jLabel4.setText(Integer.toString(time/60)); }
judge在两个向量中的元素判断是否相等,produceExpression用来生成式子的答案放入向量中;
Endjframe类用来展示正确答案以及输入的答案,并对错误的题目进行统计

小结感受:
此次实验是第一次团队合作,在一些问题的处理上,可以相互帮助,使得代码的实现比单人的更顺利,深刻体会到团队合作的重要性,为以后工作打下一点基础。
