一、前言

 

  1. 知识点:

  (1)类和对象:类(class)和对象(object)是两种以计算机为载体的计算机语言的合称。对象是对客观事物的抽象,类是对对象的抽象。类是一种抽象的数据类型。

  它们的关系是,对象是类的实例,类是对象的模板。对象是通过new classname产生的,用来调用类的方法;类的构造方法 。

  (2)对象交互:当一个对象里有多个对象的时候,那些对象之间是如何交互的,对象和对象之间的联系是如何建立的,对象如何和其他对象交流。

  (3)继承与多态:

  继承:就是保持已有类的特性而构造新类的过程。继承后,子类能够利用父类中定义的变量和方法,就像它们属于子类本身一样。

        多态:(1)一个类继承自某个父类时,对父类中的方法进行改写。

                    (2)重载是两个方法的名称相同,但参数不同,重载与多态没有关系。

                    (3)抽象类:Java语言中,用abstract 关键字来修饰一个类时,这个类叫作抽象类。抽象类是它的所有子类的公共属性的集合,是包含一个或多个抽象方法的类。 抽象类可以看作是对类的进一步抽象。在面向对象领域,抽象类主要用来进行类型隐藏。

                    (4)接口(interface)。

二、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。
 

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。

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

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。

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。
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。

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。

三、采坑心得

 

正则表达式的在三次电话计费题目中有着很大的作用,在这三次电话计费题目中对于正则表达式的使用有:

1、确定输入电话号码的位数;

2、确定开头标志符号是否正确;

3、确定输入的电话号码是否合法;

4、确定时间和日期是否正确;

5、确定区域是否准确。

String check1 = "t-0791([0-9]{7,8})\\s([0-9]{10,12})\\s\\d{4}\\.([1-9]|1[012])\\.([1-9]|([1-2][0-9])|[3][0,1])\\s((0[0-9])|(1[0-9])|(2[0-3])):([0-5][0-9]):([0-5][0-9])\\s\\d{4}\\.([1-9]|1[012])\\.([1-9]|([1-2][0-9])|[3][0,1])\\s((0[0-9])|(1[0-9])|(2[0-3])):([0-5][0-9]):([0-5][0-9])";
            String check2 = "0791([0-9]{7,8})";
String check1 = "t-0791([0-9]{7,8})\\s([0-9]{10,12})\\s\\d{4}\\.([1-9]|1[012])\\.([1-9]|([1-2][0-9])|[3][0,1])\\s((0[0-9])|(1[0-9])|(2[0-3])):([0-5][0-9]):([0-5][0-9])\\s\\d{4}\\.([1-9]|1[012])\\.([1-9]|([1-2][0-9])|[3][0,1])\\s((0[0-9])|(1[0-9])|(2[0-3])):([0-5][0-9]):([0-5][0-9])";
            String check2 = "u-1([0-9]{10})\\s1";
            String check3 = "t-0791([0-9]{7,8})\\s1([0-9]{10})\\s\\d{3,4}\\s\\d{4}\\.([1-9]|1[012])\\.([1-9]|([1-2][0-9])|[3][0,1])\\s((0[0-9])|(1[0-9])|(2[0-3])):([0-5][0-9]):([0-5][0-9])\\s\\d{4}\\.([1-9]|1[012])\\.([1-9]|([1-2][0-9])|[3][0,1])\\s((0[0-9])|(1[0-9])|(2[0-3])):([0-5][0-9]):([0-5][0-9])";
            String check4 = "t-1([0-9]{10})\\s\\d{3,4}\\s([0-9]{10,12})\\s\\d{4}\\.([1-9]|1[012])\\.([1-9]|([1-2][0-9])|[3][0,1])\\s((0[0-9])|(1[0-9])|(2[0-3])):([0-5][0-9]):([0-5][0-9])\\s\\d{4}\\.([1-9]|1[012])\\.([1-9]|([1-2][0-9])|[3][0,1])\\s((0[0-9])|(1[0-9])|(2[0-3])):([0-5][0-9]):([0-5][0-9])";
            String check5 = "07((9[0-9])|(01))";
            String check7 = "t-1([0-9]{10})\\s\\d{3,4}\\s1([0-9]{10})\\s\\d{3,4}\\s\\d{4}\\.([1-9]|1[012])\\.([1-9]|([1-2][0-9])|[3][0,1])\\s((0[0-9])|(1[0-9])|(2[0-3])):([0-5][0-9]):([0-5][0-9])\\s\\d{4}\\.([1-9]|1[012])\\.([1-9]|([1-2][0-9])|[3][0,1])\\s((0[0-9])|(1[0-9])|(2[0-3])):([0-5][0-9]):([0-5][0-9])";
            String check8 = "0791([0-9]{7,8})";
String check2 = "[u][-]1[3-9]\\d{9}[ ][3]";
            String messagejudge = "m-1[3-9]\\d{9} 1[3-9]\\d{9} [a-z|0-9| |,|.]++";

 

四、改进建议

 

7-1 电信计费系列1-座机计费

 

 7-1 电信计费系列2-手机+座机计费

 

 

 

 

 

 7-1 电信计费系列3-短信计费

 

 

 

 

五、总结

对本阶段(10-16周)综合性总结:对java的类和对象了解更加深刻,代码的优化程度有所提高,程序的可读性更好,但对于Java的熟练程度有待提高,Java编码的思路还有待加强,还是过于依赖之前C语言的固有思维。
