1.前言

该bolg将对近三次的大作业进行总结与分析。近三次大作业主要写了电信计费系统的主要功能，第一次大作业是座机计费功能，第一次电信计费题量不多，只有两题，电信计费第一次设计时较难，另一题比较简单。题第二次大作业总共有三题，电信计费是在第一次座机的基础上新增加了手机计费功能，另外两题比较简单。第三次大作业总共有三题，电信计费是增加短信计费的功能。这三次大作业主要考察了：类的设计，正则表达式。

2.设计与分析

7-1 电信计费系列1-座机计费

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。

输入格式:

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，
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
座机号码除区号外由是7-8位数字组成。
本题只考虑计费类型0-座机计费，电信系列2、3题会逐步增加计费类型。
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。
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。
注意：
本题非法输入只做格式非法的判断，不做内容是否合理的判断（时间除外，否则无法计算），比如：
1、输入的所有通讯信息均认为是同一个月的通讯信息，不做日期是否在同一个月还是多个月的判定，直接将通讯费用累加，因此月租只计算一次。
2、记录中如果同一电话号码的多条通话记录时间出现重合，这种情况也不做判断，直接 计算每条记录的费用并累加。
3、用户区号不为南昌市的区号也作为正常用户处理。

输出格式:

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。
每条通讯信息单独计费后累加，不是将所有时间累计后统一计费。
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。

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。
 

image.png

                                        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）。
 

后续扩展说明：
后续题目集将增加手机用户，手机用户的计费方式中除了与座机计费类似的主叫通话费之外，还包含市外接听电话的漫游费以及发短信的费用。在本题的设计时可统一考虑。
通话记录中，手机需要额外记录拨打/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
短信的格式：m-主叫号码，接收号码，短信内容
m-18907910010 13305862264 welcome to jiangxi
m-13305862264 18907910010 thank you

分析：按着给的类图写，还有要注意区号有三位的

7-1 电信计费系列2-手机+座机计费

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。

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。
 

建议类图：
参见图1、2、3：

image.png
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。
 

image.png
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。
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）。
注意：以上图中所定义的类不是限定要求，根据实际需要自行补充或修改。

输入样例:

在这里给出一组输入。例如：

u-13811111111 1
t-13811111111 0791 13811111110 020 2022.1.3 08:00:00 2022.1.3 08:09:20
end

13811111111 3.0 82.0

分析：本次还是按照给的类图写，并且新加入了手机，该题首需要建立User类，里面包含了建户的基本信息，号码，计费类型等属性。

7-1 电信计费系列3-短信计费

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：

image.png

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。
 

image.png

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。
 

image.png

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）。
 

注意：以上图中所定义的类不是限定要求，根据实际需要自行补充或修改。

分析：这次只需要写短信计费就行

3.踩坑心得

1.正则表达式还是很容易出现错误

2.数据进行处理时，代码的复杂度过高时，每次新增功能时都很麻烦。

3.没有考虑一些较为特殊的情况，如区号为三位

4.最后的短信计费可能因为代码过长无法提交

4.改进建议

多分几个类，以此提高代码复用率，减少代码的复杂性。使用父类，抽象类，对代码进行忧化。

5.总结

在这几周最大的收获就是了解了许多设计模式，也明白了设计模式的重要性， 设计模式是一套经过反复使用的代码设计经验，目的是为了重用代码、让代码更容易被他人理解、保证代码可靠性。在后续的学习中多了解设计模式并将其用于代码中提高代码质量。
