标签：页面   sys   system   总结   设计文档   cut   exce   Servle   驼峰   

需求分析：从收费的起点到终点收费系统                                                 时间：3minutes

设计文档：3个label 2个button 1个comboBox                                               时间：5minutes

设计复审：李娟娟复审                                                                             时间：20minutes                                       

代码规范：使用驼峰式命名                    时间：3minutes                                      

具体设计： 输入两个数字得出正确的结果             时间 2minutes

具体编码如下：                                                                                      时间：1.5taday

窗体界面：

　窗口界面：项目总结分析：这个项目因为涉及到一个最短路径的问题。

代码复审:在头脑里过一遍代码                       时间:3minutes

测试:弹出的页面执行结果正确                      时间:2minutes

测试报告:没有问题功能实现                        时间:1minutes

计算工作量:                                                时间:2taday

总结:多动手是可以快速找出自己的问题所在
