二、题目分析总结
1.题目集08：7-1 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。
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）。

2.题目分析：本题是电信计费系列的第一题，也是相对后面两题难度最大的一题，因为需要根据所给的类图构建本系列题目的大体框架，后续题目再在框架上继续延伸扩展，设计难度和代码量较大。
本题需要注意的有以下几个点：
1.输入格式的正则表达式，要注意日期的合法性。
2.根据题目要求，忽略重复开户的操作。
3.具体实现思路：
创建一个可储存用户的容器，判断输入的信息，如果判断为开户信息，再判断容器中是否存在相同的账户号码，不存在则在容器中添加该用户，如果判断为通话信息，在判断拨打号码和收听号码是否是容器中的号码，若是则将
拨打(收听)信息存入用户中的储存相应信息的容器中。最后的计费则是将用户里的每条拨打信息的时间提取出来进行计算即可。
4.遇到的bug
因为座机计费规则还是比较简单，并且只有座机与座机的通话所以没有遇到很大的bug,只遇到了将通讯时间计算错误，以及日期的正则表达式错误两个较小的bug。
2.7-1 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。

1.题目分析：本题的计费形式对于上一题多了很多种，主要是手机的计费规则多了省内漫游和省外漫游。
本题需要注意以下几点：
1.手机计费根据哪套规则记录费用不是按照开户时的地址进行计算，而是根据拨打人拨打时所在的区号以及接听人接听所在区号进行计费。
实现思路：在上题的基础上，增加储存手机用户的容器，增加相应手机计费规则，以及判断手机通讯信息的正则表达式，储存手机用户的方式和上题储存座机用户的方式基本一致，根据拨打人所在区号根据接听人的区号判断是市内省内还是国内长途信息等类型，在用户信息里建立对应的容器储存它们。
3.遇到的bug
这道题遇到bug的原因大多是在计费方面，由于存在座机打手机，手机打手机，手机打座机等，所以在数据储存时，他们的信息格式各不相同，出现了一些信息储存错误的小bug。
3.7-1 电信计费系列3-短信计费
其他题目信息与上题相同，主要多了以下内容：
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。
3、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.

这个学期的JAVA编程学期收获颇多，面向对面的设计能力得到了巨大的提升，这次的学期对以后大二大三的的学习肯定能提供巨大的帮助，但在某些方面还需改进，如多态、抽象类、接口方面还需要进一步的深入学习，总的概括如下：
1：学到了什么：
①：可以根据需求分析来解决问题。
②：对面向对象的能力得到了提升。
③：能通过类间关系来降低代码的耦合性。
④：抽象类与堕胎方法的使用。
⑤：对书上后几个章节得到了学习，了解到了 各种在实际的JAVA编程方法（如JAVAFX、正则表达式，各种方法（如：Hashset、Array list等等））
2：需要进一步改进的地方：
①：自主学习的能力，由于这门课程采用的是线上线下相结合的方式，通过老师指定
的方式或其他方式自学是很重要的。
②：编码时的调试能力，在pta作业的完成中，错误无可避免，但是要学会自己通过调
试来发现问题所在并解决它。
③：对简便的追求要给与肯定，越复杂的题目越要追求简单化，从而获得更加好的交互体验，让程序更加 有可用性。
