第三次博客作业

- 改进建议
- 总结
前言
（总结之前所涉及到的知识点、题量、难度等情况）
我认为这三次PTA作业较为简单，非常人性化，每道题都给了类图，都不怎么要动脑子了 ，
所涉及的知识点还是比较广的，但是并不难，题量也不多，每一次就两三道，
主要是电信计费系列的三次迭代题。
设计与分析
（重点对题目的提交源码进行分析，可参考SourceMonitor的生成报表内容以及PowerDesigner的相应类图，要有相应的解释和心得（做到有图有真相），本次Blog必须分析PTA中的三个资费题目）
7-1 电信计费系列1-座机计费
我认为该题主要考察类间关系的设计以及如何利用正则表达式对输入的字符串进行特判。
还有就是利用Arraylist对字符串进行存储。本来设计类间关系是该题最为困难的环节但是
老师在出题时已经将类图基本给出，所以难点转变为了如何利用正则表达式对输入的字符串进行特判。
（在Main函数中）我之前几次提交也是在特判上出了一点问题。
（下面是已经给出的类图）

7-1 电信计费系列2-手机+座机计费
该题为上一题的迭代，类间设计基本不变，就是加了一个手机计费设计,
要区分座机计费与手机计费，同时对手机计费要对计费方式进行重新设计。

第三题较为简单就不加以累述了。就是加一个电信计费就行。
（类图如下）
踩坑心得
（对源码的提交过程中出现的问题及心得进行总结，务必做到详实，拿数据、源码及测试结果说话，切忌假大空）
第3次在设计的时候算法出了一点问题，信息存储其实没有出问题，就是算钱的时候出了一点问题，但是后面自己通过测试点改过来了
第2次的问题一直没有找出来，但是我觉得应该是在时间的特判上出了问题
改进建议
（对相应题目的编码改进给出自己的见解，做到可持续改进）
具体怎么改进，我自己本身也不是很清楚，但我觉得代码风格一定要简约，
同时对函数的构造以及类的分类必须清晰，要不然一旦出现格式错误，
很难在短时间内发现自己代内部的问题，
在构造类的过程中，命名尽量贴合实际，切记不要随意命名，变量名也应尽量切合题意，
这样做可以极大程度的方便后续代码的维护以及修改。
同时在书写代码的时候，量在关键处，尤其是逻辑紧密的地方加上一定量的注释，
这样做既可以方便自己后续的阅读，也可以方便别人对代码进行理解
而且要加强对字符串这方面的练习，包括正则表达式的练习，在这方面还有着较大的漏洞
总结
（对本阶段（12-15周）综合性总结，学到了什么，哪些地方需要进一步学习及研究，对教师、课程、作业、实验、课上及课下组织方式等方面的改进建议及意见。2.在截止时间之前将发布的Blog正文网址链接（非编辑网址链接）直接发到超星系统即可）
对于本阶段的综合训练，我觉得自己在类间设计这一块还需要下功夫，
对于类之间的理解以及调用仍然不太熟悉，当然了在正则上面的使用也有一些欠缺，
对于字符串的特判有时还是会出现一些问题
