Blog3：nchu-software-oop-2022-6~8
一、前言
不知不觉，已到了本学期末尾，面向对象程序设计这门课也已经结课。课程虽然结束了，但需要学习和巩固的知识点还有很多。同时，这也是最后一次blog总结。这次Blog主要针对PTA6~8次大作业中的电信计费系列的题目进行总结。该系列重点是考查了正则表达式的正确使用，对类图的分析能力（即借助类图去编写代码，完成题目要求），抽象类和与其子类的继承关系，还有集合框架List相关练习。涉及的内容比较多，整套题目都感觉十分复杂。但是这系列题目将我们学习的内容融合在一起，锻炼我们的整体能力。比如在电信计费简化版本--座机计费题目中，我们要知道怎么处理那些通话记录--即首先运用split方法和substring等知识去将输入的通讯信息分开，分别得到用户开户的信息及其号码，然后才能创建一个用户，对于每条通讯信息需要用ArrayList去一一储存。该系列第二题是在原基础上加手机用户的参与，要创建新的手机用户类等等。在电信计费的题目中也接触学习到了一些新知识，比如时间需要Date类，才能进行差的计算，也熟练掌握了增强for循环的运用。
二、设计与分析
题目1：
7-1 电信计费系列1-座机计费 分数 80 作者 蔡轲 单位 南昌航空大学实现一个简单的电信计费程序：
假设南昌市电信分公司针对市内座机用户采用的计费方式：
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。
南昌市的区号：0791，江西省内各地市区号包括：0790~0799以及0701。
建议类图：
参见图1、2、3，可根据理解自行调整：
图1
图1中User是用户类，包括属性：
userRecords （用户记录）、balance（余额）、chargeMode（计费方式）、number（号码）。
ChargeMode是计费方式的抽象类：
chargeRules是计费方式所包含的各种计费规则的集合，ChargeRule类的定义见图3。
getMonthlyRent（）方法用于返回月租（monthlyRent）。
UserRecords是用户记录类，保存用户各种通话、短信的记录，
各种计费规则将使用其中的部分或者全部记录。
其属性从上到下依次是：
市内拨打电话、省内（不含市内）拨打电话、省外拨打电话、
市内接听电话、省内（不含市内）接听电话、省外接听电话的记录
以及发送短信、接收短信的记录。
图2
图2中CommunicationRecord是抽象的通讯记录类：
包含callingNumber拨打号码、answerNumber接听号码两个属性。
CallRecord（通话记录）、MessageRecord（短信记录）是它的子类。
CallRecord（通话记录类）包含属性：
通话的起始、结束时间以及
拨号地点的区号（callingAddressAreaCode）、接听地点的区号（answerAddressAreaCode）。
区号用于记录在哪个地点拨打和接听的电话。座机无法移动，就是本机区号，如果是手机号，则会有差异。
图3
图3是计费规则的相关类，这些类的核心方法是：
calCost（ArrayList<CallRecord> callRecords）。
该方法针根据输入参数callRecords中的所有记录计算某用户的某一项费用；如市话费。
输入参数callRecords的约束条件：必须是某一个用户的符合计费规则要求的所有记录。
LandPhoneInCityRule、LandPhoneInProvinceRule、LandPhoneInLandRule三个类分别是
座机拨打市内、省内、省外电话的计费规则类，用于实现这三种情况的费用计算。
（提示：可以从UserRecords类中获取各种类型的callRecords）。

电信系列1
这一次题目要求我们仅仅只针对座机对于座机的拨打与接受，以南昌市的座机作为背景，进行电信计费的模拟。题目对于计费有一定的条件限制，这也是我们需要注意的地方，然后，根据题目设计好了user类和需要判断日期和计算时间的类，还有记录通话记录的类、设备类作为座机的父类。然后再去按照输入输出去设计Main类里的一些判断和与其他类的交互，中途很多次添加了一些额外判断去忽略那些错误输入。
题目2：
7-1 电信计费系列2-手机+座机计费 分数 80 作者 蔡轲 单位 南昌航空大学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

电信系列2
该题首先要建立User类，里面包含了建户的基本信息，号码，计费类型等属性。接着还需要一个类可以接收信息，处理信息，并将其所读取到的信息进行分别存储到两个容器。然后将分类好的信息对应到每个用户之中，用UserRecord类来记录。通过对比输入信息中的号码与用户的开户号码，将通讯信息对应到每个用户下面，之后通过一系列计算将用户的电信费用展示出来。其中还需要我们创建新类，计算电话的时间差，以此来计算总费用，还要将ArrayList里的重复元素去掉。
题目3：
7-1 电信计费系列3-短信计费 分数 50 作者 蔡轲 单位 南昌航空大学实现一个简单的电信计费程序，针对手机的短信采用如下计费方式：
1、接收短信免费，发送短信0.1元/条，超过3条0.2元/条，超过5条0.3元/条。
2、如果一次发送短信的字符数量超过10个，按每10个字符一条短信进行计算。
输入：
输入信息包括两种类型
1、逐行输入南昌市手机用户开户的信息，每行一个用户。
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 3-手机短信计费）
例如：u-13305862264 3
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。
本题只针对类型3-手机短信计费。
2、逐行输入本月某些用户的短信信息，短信的格式：
m-主叫号码，接收号码，短信内容 （短信内容只能由数字、字母、空格、英文逗号、英文句号组成）
m-18907910010 13305862264 welcome to jiangxi.
m-13305862264 18907910010 thank you.
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：
根据输入的详细短信信息，计算所有已开户的用户的当月短信费用（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。
本题只做格式的错误判断，无需做内容上不合理的判断，比如同一个电话两条通讯记录的时间有重合、开户号码非南昌市的号码、自己给自己打电话等，此类情况都当成正确的输入计算。但时间的输入必须符合要求，比如不能输入2022.13.61 28:72:65。
本题只考虑短信计费，不考虑通信费用以及月租费。
建议类图：
参见图1、2、3：
图1
图1中User是用户类，包括属性：
userRecords （用户记录）、balance（余额）、chargeMode（计费方式）、number（号码）。
ChargeMode是计费方式的抽象类：
chargeRules是计费方式所包含的各种计费规则的集合，ChargeRule类的定义见图3。
getMonthlyRent（）方法用于返回月租（monthlyRent）。
UserRecords是用户记录类，保存用户各种通话、短信的记录，
各种计费规则将使用其中的部分或者全部记录。
其属性从上到下依次是：
市内拨打电话、省内（不含市内）拨打电话、省外拨打电话、
市内接听电话、省内（不含市内）接听电话、省外接听电话的记录
以及发送短信、接收短信的记录。
图2
图2中CommunicationRecord是抽象的通讯记录类：
包含callingNumber拨打号码、answerNumber接听号码两个属性。
CallRecord（通话记录）、MessageRecord（短信记录）是它的子类。
图3
图3是计费规则的相关类，这些类的核心方法是：
calCost（ArrayList callRecords）。
该方法针根据输入参数callRecords中的所有记录计算某用户的某一项费用；如市话费。
输入参数callRecords的约束条件：必须是某一个用户的符合计费规则要求的所有记录。
SendMessageRule是发送短信的计费规则类，用于计算发送短信的费用。
LandPhoneInCityRule、LandPhoneInProvinceRule、LandPhoneInLandRule三个类分别是座机拨打市内、省内、省外电话的计费规则类，用于实现这三种情况的费用计算。
（提示：可以从UserRecords类中获取各种类型的callRecords）。

三、踩坑心得
1、在写给出类图题时，天真地以为给出的是完整的类图，没有进行思考就敲代码去了，到后面根本搞不清楚思路。所以说拿到题目应该把大致的方向找好。
2、关于类相关的知识点很多，由于对于类与类之间的种种关系掌握的并不好，所以在写代码时，整体的框架都很混乱，思路也不清晰。
3、这个系列题型用到了正则表达式，对于正则表达式的使用并不熟练，在这方面卡壳了好久。
4、在计算价钱时，由于未把时间转换成int型，导致后面出现误差，造成报错，这个小东西太磨人了，找了好久才发现这个问题。
四、代码改进建议
1、很多知识点使用起来十分的不熟练，写得很繁琐，希望可以通过更多的学习提高自己的能力。
2、重新设计新的类，包括了新的数据存放数组和方法，节省代码空间。
3、多做继承应用之类的题目，不能第一时间反应出来总归到底是做的题目不够写的代码太少了。
4、对于正则表达式的运用不够熟练，对于Java的集中设计原则不会合理的运用，对于一些集合类的掌握程度不高，每次作业花费的时间较长，需要查阅大量的资料才能解决问题，作业的成功率不高，得到的分数不高。解决方法：遇到不懂的知识点上网查阅资料，请教他人，多看书记住一些基本的知识点。
五、总结
通过本学期的PTA作业学会了正则表达式的使用。正则表达式是一种可以用于模式匹配和替换的强有力的工具，可以看成是多个字符的组成规则。了解到Java中存放对象的三种类型的集合：Set（集）List（表）Map（映射）。Set是最简单的集合，集合中的对象排序是没有特定方式的，并且没有重复的对象，Set的接口的两个主要实现类是：HashSet和TreeSet。HashSet：按照哈希算法来存取集合中的对象，HashSet会调用对象的hashCode（）方法获得哈希码，从而算出对象在集合中的位置。TreeSet：采用树结构来存储数据，每一个元素都是一个节点，一层一层的依次排列。List以线性方式存储元素，允许集合中存放重复元素。List接口的主要实现来是ArrayList和LinkedList。Map：集合中的每一个元素包含一对键对象和值对象，集合中的键对象不能重复，值对象可以重复。HashMap按照哈希算法来存取键值对象。Java中的集合类能够使程序方便的存储和操纵数目不固定的一组数据。
面向对象编程不能注重于按步骤一步一步解决问题，而应该注重于将问题中的部分分成各个对象，各司其职，谁做了什么事，谁又做了什么事，他们共同作用的结果解决了一件事。可以说，面向对象编程更接近现实世界。
