第三次博客作业
1|0前言:
题目集六:
电信计费系列一,难度较前几次的数学计算有所下降,但是更为繁琐。
题目集七:
电信计费系列二在系列一上面添加了手机计费规则,规则更加灵活,但是整体难度仍然不大,由于系列一搭好了框架,繁琐程度大大的降低了。
题目集八:
电信计费系列三添加了短信的计费规则,更加灵活了,尤其是对手机号和短信内容的处理。
2|0设计与分析:
2|17-1 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。
1|0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。
1|0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。
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

本次作业主要是针对类图结构写代码,十分繁琐。,看懂类图并用提供的类图写代码便成为这道题难点。题目算法不难,各项指标都处于一个较为合理的范围。
2|27-1 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:
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。

1|0类图与分析
本次作业主要是加入了手机业务,数据处理更加复杂了。最大复杂度和深度超出了合理范围。还有非常大的改进空间。
2|37-1 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:
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)。
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。

1|0类图与分析
由于本次代码是由上次的基础上添加而来,所以也继承了复杂度过高的问题,有非常大的改进空间。
3|0采坑心得
- 座机号有3位的,如北京区号为010,记得区分
- 正则匹配的时候,应该用较复杂的正则进行校验是否存在,再用比较简单的正则进行捕获。
- 时间之间的计算可以用getTime()方法相减,得出的是它们相差的秒数。
4|0改进建议
整个系列的代码都存在复杂度过高的问题,改进空间非常大,增加代码易读性的路程任重道远。
5|0总结:
老师最近几周讲起了代码规范性和结构的设计等,对把代码设计好有一定的帮助。下一步打算用老师讲的javafx把我的农夫过河实验给做好。
