复利项目之结对2.0

结对同伴的学号：201406114245

姓名：赵创佳

博客地址：http://www.cnblogs.com/7763255qw/ ；github地址： https://github.com/zhaochuangjia

程序源代码已上传至https://github.com/ganjiaping

源程序的文件名为：Team2.java

一、项目简介

项目名称：复利计算再升级

版本：结对2.0

版本类型：java/jar/apk

使用工具：Eclipse Swing插件/JAVA模拟器

主要功能：复利单利的计算、贷款的计算以及投资的计算

二、新的功能需求

客户在大家的引导下，有了更多的想法：

这个数据我经常会填.....帮我预先填上呗？......
把界面做得简单漂亮好操作一点呗？
能不能帮我转成个APP，我装到手机上就更方便了？
我觉得这个很有用，很多人可能都需要这些功能，做到我的微信公众号上吧？
能不能不要让我填表单，让我发条消息，或者对着手机说句话就可以了？

每组选一两个方向加以改进，让我们的投资计算与记录工具，达到可以发布给用户使用的版本。

根据我和我结对队友的能力，我们小组选的是：

把项目的界面做得更简单、漂亮、好操作；

将项目文件.java形式转成.jar形式，再转成.apk形式。

三、TSP data (即估计实现所需时间和结对编程时间)

TSP data 项目耗时记录表
TSP	软件项目阶段	花费时间
Planning	计划	11
Estimate	估计这个任务需要多少时间	11
Development	开发	2
Analysis	需求分析	1
Design Spec	生成设计文档	1
Design Review	设计复审(和同事审核设计文档)	1
Coding Standard	代码规范(为目前的开发制定合适的规范)	1
Design	具体设计	1
Coding	具体编码	1
Code Review	代码复审	1
Test	测试(自我测试，修改代码，提交修改)	2

四、任务分配

这个结对编程过程中，我做了把项目的界面做得更简单、漂亮、好操作；

同伴做了将项目文件.java形式转成.jar形式，再转成.apk形式。

五、总结这次结对编程的收获到和感悟：

本次结对项目主要是实现复利项目界面的优化，以及将项目文件.java形式转成.jar形式，再转成.apk形式。我们用Eclipse Swing插件编程实现界面的优化、JAVA模拟器实现形式转换，大致上基本实现了这两个功能。

老师给出的功能选项对我们小组来说，很有挑战性。根据我和同伴的能力，我们就选了我们能实现的功能来做这次结对的项目。但是只是完成任务对我以及我的同伴来说是不够的，因为我们一起讨论了很多想法，可能由于能力和时间的不足，而导致一些不错的想法都未能来得及实现。但之后，我们会继续改进程序，并将项目做到最好。

总的来说，这次的结对编程就我个人看来，不是很理想。因为没有把老师给出的五个功能都实现，虽然，已经完成了这次结对项目的要求，但我想去实现其他的我们这次项目没选的功能。我想我和我的同伴后续会对这个项目不断的改进，然后得到自己想要的效果，即把所有功能实现，还有做到最好。

最后，感谢我的同伴在这次合作中的付出，我衷心的感谢！还有下次我们会做的更好！
