第三次java阶段性总结

一、总结前言

本次总结是关于笔者这一段时间Java学习内容的总结，涉及到最近三次PTA大作业，题目主题是电信计费，相比之前的点线型要简单不少。

二、设计与分析

第六次和第七次的大作业属于继承关系，所以就只选择第七次进行解析。

题目：

实现南昌市电信分公司的计费程序，假设该公司针对手机和座机用户分别采取了两种计费方案，分别如下：
1、针对市内座机用户采用的计费方式（与电信计费系列1内容相同）：
月租20元，接电话免费，市内拨打电话0.1元/分钟，省内长途0.3元/分钟，国内长途拨打0.6元/分钟。不足一分钟按一分钟计。
假设本市的区号：0791，江西省内各地市区号包括：0790~0799以及0701。
2、针对手机用户采用实时计费方式：
月租15元，市内省内接电话均免费，市内拨打市内电话0.1元/分钟，市内拨打省内电话0.2元/分钟，市内拨打省外电话0.3元/分钟，省内漫游打电话0.3元/分钟，省外漫游接听0.3元/分钟，省外漫游拨打0.6元/分钟；
注：被叫电话属于市内、省内还是国内由被叫电话的接听地点区号决定，比如以下案例中，南昌市手机用户13307912264在区号为020的广州接听了电话，主叫号码应被计算为拨打了一个省外长途，同时，手机用户13307912264也要被计算省外接听漫游费：
u-13307912264 1
t-079186330022 13307912264 020 2022.1.3 10:00:25 2022.1.3 10:05:11

输入：
输入信息包括两种类型
1、逐行输入南昌市用户开户的信息，每行一个用户，含手机和座机用户
格式：u-号码计费类型（计费类型包括：0-座机 1-手机实时计费 2-手机A套餐）
例如：u-079186300001 0
座机号码由区号和电话号码拼接而成，电话号码包含7-8位数字，区号最高位是0。
手机号码由11位数字构成，最高位是1。
本题在电信计费系列1基础上增加类型1-手机实时计费。
手机设置0或者座机设置成1，此种错误可不做判断。
2、逐行输入本月某些用户的通讯信息，通讯信息格式：
座机呼叫座机：t-主叫号码接听号码起始时间结束时间
t-079186330022 058686330022 2022.1.3 10:00:25 2022.1.3 10:05:11
以上四项内容之间以一个英文空格分隔，
时间必须符合"yyyy.MM.dd HH:mm:ss"格式。提示：使用SimpleDateFormat类。
输入格式增加手机接打电话以及收发短信的格式，手机接打电话的信息除了号码之外需要额外记录拨打/接听的地点的区号，比如：
座机打手机：
t-主叫号码接听号码接听地点区号起始时间结束时间
t-079186330022 13305862264 020 2022.1.3 10:00:25 2022.1.3 10:05:11
手机互打：
t-主叫号码拨号地点接听号码接听地点区号起始时间结束时间
t-18907910010 0791 13305862264 0371 2022.1.3 10:00:25 2022.1.3 10:05:11

注意：以上两类信息，先输入所有开户信息，再输入所有通讯信息，最后一行以“end”结束。

输出：
根据输入的详细通讯信息，计算所有已开户的用户的当月费用（精确到小数点后2位，单位元）。假设每个用户初始余额是100元。
每条通讯、短信信息均单独计费后累加，不是将所有信息累计后统一计费。
格式：号码+英文空格符+总的话费+英文空格符+余额
每个用户一行，用户之间按号码字符从小到大排序。
错误处理：
输入数据中出现的不符合格式要求的行一律忽略。

三、踩坑心得

这三次大作业还是踩到了坑的，比如第七次大作业，笔者做的时候因为一个bug一直通不过去，通过debug一步一步慢慢的查慢慢的看才找到是在前面计费种类错了把手机的计费记作了座机的计费，所以在设计的时候一定要明确，在第三个题目集的计算中，需要注意短信的长度，根据短信的长度计算不同的收费。

四、改进建议

改进意见的话就是题目可以稍微严谨一点，可以多给一些测试样例，希望可以多多给些类图，方便打出框架。可以考虑采用继承的方法去实现对手机，座机信息的提取和判断，从而减少代码的重复。

五、总结

总的来说，这三次大作业难度对于我来说还是很高的，也没有完成的很好，仅仅是及格线边缘，希望后续的学习中我能够攻克这一部分的知识，再多多做类似的题目，提高自己的java编程能力。也希望老师可以多多讲解一些相关题目，方便更好理解。
