一、前言
6-8的大作业主要是实现电信计费系统。
二、设计与分析
-
6-7-1 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。
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)。

思路
首先搞清楚类图中每个类的功能,和每个类其中的方法都能实现什么,这样就完成了一半以上了,因为这个题目我感觉最大的难点就在与无法得到准确的正则表达式,进行输入数据是否符合要求的。还有就是要注意有的区号是三个字符的。
-
类图
-
代码复杂度
-
改进建议
这题我是没拿到满分的,当时还有4个点没过,我感觉是正则表达式出现了问题,因为在后面第7次作业的时候我全部点都过了,思路还是使用在这题一样的思路,唯一改变的只有正则表达式,所以我建议可以修改下正则表达式,当然也可以直接在下面题目中拿正则表达式。

7-7-1 电信计费系列2-手机+座机计费
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

思路分析
在上一次作业没有的的作业没有满分后,我选择了删除整个项目,然后重新编写,最后还是发现问题出现在了正则表达式上面。

改进建议
我这次是使用面对抽象层来进行编码的,不过还有有些问题,就比如有些应该单独放在特定子类的属性和方法,我选择了编写的方便直接放在父类中,减少了代码的工作量,但是如果后期相对代码进行扩展和修改就会有点麻烦,所以有兴趣的话,也可以去修改下我上面父类的属性和代码。

8-7-1 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。

太简单,没有建议,唯一要注意就是短信有合法符号范围限定。
总结
JAVA课程到这里也应该算正式结束了,我也收获到了很多,自我感觉还算掌握了面对对象编程的思想。
