移动业务资费问题的总结性Blog
一、前言
1、经过了这几周的学习（12-15）周，我们学习了java的封装、继承、多态、接口、抽象类、集合框架，javaFX，java项目编程原则：单一职责原则，里氏替换原则，依赖倒置原则，接口隔离原则，迪米特法则(最少知道原则)，开闭原则，正则表达式，lamba表达式，内部类，逻辑思维能力，全面考虑问题的能力，方法编写能力等知识。
2、我们在pta主要做移动业务资费问题，一共三题，分别为迭代作业。由于老师给了类图，所以难度降低了一点（但是对我来说，还是困难），第一题写的很困难，但是如果你写完后，后面会更简单。
3、我的做题时间比较长，因为我基础不太好，但是最后也写完了，在同学和百度的帮助下。
二、设计与分析
1.7-1 电信计费系列1-座机计费
***题目信息如下：
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。

***本题一开始我吧没有思路，后来老师发了类图后，开始有了进展。
（1）首先，我先根据老师的类图，选出本题要用的座机类和关系，然后在编译工具里建好项目和类，慢慢把类补充完整，比如：
LandPhoneInCityRule，LandPhoneInLandRule，LandPhoneInProvinceRule这三个类写那三种座机的计费方式，user和userRecord，chargeMode
的继承写好，communicationRecord和callRecord的继承关系等。
(2)然后，我开始写main函数，先将正则表达式写出，本题一共要写两个，分别匹配座机的格式和通讯信息格式如下：
String s1 = "^u-\\d{11,12}\\s(0|1|2)$";
String s2="t-(\\d){11,12}\\s(\\d){11,12}\\s((((1[6-9]|[2-9]\\d)\\d{2}).([13578]|1[02]).([1-9]|[12]\\d|3[01]))|(((1[6-9]|[2-9]\\d)\\d{2}).([13456789]|1[012]).([1-9]|[12]\\d|30))|(((1[6-9]|[2-9]\\d)\\d{2})-2-([1-9]|1\\d|2[0-8]))|(((1[6-9]|[2-9]\\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))-2-29-)) (20|21|22|23|[0-1]\\d):[0-5]\\d:[0-5]\\d\\s((((1[6-9]|[2-9]\\d)\\d{2}).([13578]|1[02]).([1-9]|[12]\\d|3[01]))|(((1[6-9]|[2-9]\\d)\\d{2}).([13456789]|1[012]).([1-9]|[12]\\d|30))|(((1[6-9]|[2-9]\\d)\\d{2})-2-([1-9]|1\\d|2[0-8]))|(((1[6-9]|[2-9]\\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))-2-29-)) (20|21|22|23|[0-1]\\d):[0-5]\\d:[0-5]\\d";
（3）然后在主函数里分别写循环开户，匹配正则表达式；
在写3个if语句分别判断3种计费方式。最后，使用foreach循环输出。
我开户时使用了treeMap，开户，输出，排序等操作比较方便。
2、7-1 电信计费系列2-手机+座机计费
***题目信息如下：
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

***本题我在第一题的基础上进行编写，但是这题难度更大，计费方式更多。
（1）首先，我在第一题的基础上加上了电话计费的类，并补充完整各个类之间的关系。因为之前有座机的计费方式，所以我就只加上了 电话的计费方式，我也分了三种，根据接电话的地区进行分类，并且，它们是chargeRule的子类，user和userRecord，chargeMode
的继承写好，communicationRecord和callRecord的继承关系等进行修改，加上电话计费的内容。
（2）然后，我开始写main函数，也是先写正则表达式，一共要写6个，分别匹配座机的号码格式和手机的号码格式，以及座机打座机，
座机打手机，手机打座机，手机打手机这四种方式。
String s1 = "u-0\\d{10,11}\\s0";
String s2 = "u-1\\d{10}\\s1";
String s3 ="t-0(\\d){9,11}\\s0(\\d){9,11}\\s((((1[6-9]|[2-9]\\d)\\d{2}).([13578]|1[02]).([1-9]|[12]\\d|3[01]))|(((1[6-9]|[2-9]\\d)\\d{2}).([13456789]|1[012]).([1-9]|[12]\\d|30))|(((1[6-9]|[2-9]\\d)\\d{2})-2-([1-9]|1\\d|2[0-8]))|(((1[6-9]|[2-9]\\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))-2-29-)) (20|21|22|23|[0-1]\\d):[0-5]\\d:[0-5]\\d\\s((((1[6-9]|[2-9]\\d)\\d{2}).([13578]|1[02]).([1-9]|[12]\\d|3[01]))|(((1[6-9]|[2-9]\\d)\\d{2}).([13456789]|1[012]).([1-9]|[12]\\d|30))|(((1[6-9]|[2-9]\\d)\\d{2})-2-([1-9]|1\\d|2[0-8]))|(((1[6-9]|[2-9]\\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))-2-29-)) (20|21|22|23|[0-1]\\d):[0-5]\\d:[0-5]\\d";
String s4 = "t-0(\\d){9,11}\\s1(\\d){10}\\s0(\\d){2,3}\\s\\d{4}.\\d{1,2}.\\d{1,2}\\s\\d{2}:\\d{2}:\\d{2}\\s\\d{4}.\\d{1,2}.\\d{1,2}\\s\\d{2}:\\d{2}:\\d{2}";
String s5 = "t-1(\\d){10}\\s0(\\d){2,3}\\s0\\d{9,11}\\s\\d{4}.\\d{1,2}.\\d{1,2}\\s\\d{2}:\\d{2}:\\d{2}\\s\\d{4}.\\d{1,2}.\\d{1,2}\\s\\d{2}:\\d{2}:\\d{2}" ;
String s6 = "t-1(\\d){10}\\s0(\\d){2,3}\\s1\\d{10}\\s0\\d{2,3}\\s((((1[6-9]|[2-9]\\d)\\d{2}).([13578]|1[02]).([1-9]|[12]\\d|3[01]))|(((1[6-9]|[2-9]\\d)\\d{2}).([13456789]|1[012]).([1-9]|[12]\\d|30))|(((1[6-9]|[2-9]\\d)\\d{2})-2-([1-9]|1\\d|2[0-8]))|(((1[6-9]|[2-9]\\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))-2-29-)) (20|21|22|23|[0-1]\\d):[0-5]\\d:[0-5]\\d\\s((((1[6-9]|[2-9]\\d)\\d{2}).([13578]|1[02]).([1-9]|[12]\\d|3[01]))|(((1[6-9]|[2-9]\\d)\\d{2}).([13456789]|1[012]).([1-9]|[12]\\d|30))|(((1[6-9]|[2-9]\\d)\\d{2})-2-([1-9]|1\\d|2[0-8]))|(((1[6-9]|[2-9]\\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))-2-29-)) (20|21|22|23|[0-1]\\d):[0-5]\\d:[0-5]\\d";
（3）同第一题，然后在主函数里分别写循环开户，匹配正则表达式，分别匹配座机的号码格式和手机的号码；
在写4个if语句分别判断4种通信方式，在通信方式里写3种地区的情况（根据市内省内国内）。
最后，使用foreach循环输出。
我开户时还使用了treeMap，开户，输出，排序等操作比较方便。
3、7-1 电信计费系列3-短信计费
***题目信息如下：
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。
***题目的类图如下：
***题目代码如下：
import java.util.ArrayList; import java.util.Scanner; import java.util.TreeMap; public class Main { public static void main(String[] args) { Scanner in =new Scanner(System.in); String a = in.nextLine(); String s1 = "u-1\\d{10}\\s3"; String s2 = "m-1\\d{10}\\s1\\d{10}\\s([a-z]|[A-Z]|[0-9]|[,]|[.]|[ ]){1,}"; TreeMap<String,User> treeMap = new TreeMap<String,User>(); while(!a.equals("end")) { if(a.matches(s1)){ String[] c = a.split("-"); String[] d = c[1].split(" "); User user=new User(d[0],new MessageCharing()); treeMap.put(d[0],user); } if(a.matches(s2)) { String[] e = a.split("-"); String[] f = e[1].split(" "); MessageRecord cal = new MessageRecord (e[1].substring(24)); //if(treeMap.get(f[0])!=null&&treeMap.size()!=0){ if(treeMap.get(f[0])!=null) treeMap.get(f[0]).getUserRecords().addSendMessageRecords(cal); } //} a = in.nextLine(); } for(User user:treeMap.values()) { System.out.print(user.getNumber()+" "); System.out.printf("%.1f %.1f\n",user.calCost(),user.calBalance()); } } } abstract class ChargeMode { ArrayList<ChargeRule> chargeRules = new ArrayList<>(); public ArrayList<ChargeRule> getChargeRules() { return chargeRules; } public void setChargeRules(ArrayList<ChargeRule> chargeRules) { this.chargeRules = chargeRules; } public double calCost(UserRecords userRecords) { return 0; } } abstract class ChargeRule { public abstract double calCost(ArrayList<MessageRecord> sendMessageRecords); // TODO 自动生成的方法存根 } abstract class CommunicationRecord { protected String callingNumber; protected String answeringNumber; public String getCallingNumber() { return callingNumber; } public void setCallingNumber(String callingNumber) { this.callingNumber = callingNumber; } public String getAnsweringNumber() { return answeringNumber; } public void setAnsweringNumber(String answeringNumber) { this.answeringNumber = answeringNumber; } } abstract class MessageChargeRule extends ChargeRule{ public double calCost(UserRecords userRecords) { // TODO 自动生成的方法存根 return 0; } } class MessageCharing extends ChargeMode { public double calCost(UserRecords userRecords){ getChargeRules().add(new SendMessageRule()); double ans =0; double a = super.getChargeRules().get(0).calCost(userRecords.getSendMessageRecords()); ans = a+ans; return ans; } } class MessageRecord extends CommunicationRecord{ private String message; public String getMessage() { return message; } public void setMessage(String message) { this.message = message; } public MessageRecord(String message) { super(); this.message = message; } } class SendMessageRule extends ChargeRule{ @Override public double calCost(ArrayList<MessageRecord> sendMessageRecords) { // TODO 自动生成的方法存根 int sum = 0; for(MessageRecord b: sendMessageRecords) { sum += (int)(Math.ceil(b.getMessage().length()/10.0)); } if(sum<=3) return sum*0.1; else if(sum<=5) return 0.3+(sum-3)*0.2; else return 0.7+(sum-5)*0.3; } } class User { UserRecords userRecords = new UserRecords(); private double balance = 100 ; private ChargeMode chargemode; private String number; public User(String number,ChargeMode chargemode ) { // TODO 自动生成的构造函数存根 this.chargemode = chargemode; this.number=number; } public double getBalance() { return balance ; } public UserRecords getUserRecords() { return userRecords; } public void setUserRecords(UserRecords userRecords) { this.userRecords = userRecords; } public double calBalance() { return balance-chargemode.calCost(userRecords); } public double calCost() { return chargemode.calCost(userRecords); } public ChargeMode getChargemode() { return chargemode; } public void setChargemode(ChargeMode chargemode) { this.chargemode = chargemode; } public String getNumber() { return number; } public void setNumber(String number) { this.number = number; } } class UserRecords { ArrayList<MessageRecord> sendMessageRecords = new ArrayList<MessageRecord>(); ArrayList<MessageRecord> receiveMessageRecords = new ArrayList<MessageRecord>(); public ArrayList<MessageRecord> getSendMessageRecords() { return sendMessageRecords; } // public void setSendMessageRecords(ArrayList<MessageRecord> sendMessageRecords) { // this.sendMessageRecords = sendMessageRecords; // } public ArrayList<MessageRecord> getReceiveMessageRecords() { return receiveMessageRecords; } // public void setReceiveMessageRecords(ArrayList<MessageRecord> receiveMessageRecords) { // this.receiveMessageRecords = receiveMessageRecords; // } public void addSendMessageRecords(MessageRecord sendMessageRecord) { sendMessageRecords.add(sendMessageRecord); } public void addReceiveMessageRecords(MessageRecord receiveMessageRecord) { receiveMessageRecords.add(receiveMessageRecord); } }
***本题因为有了前两题的基础，所以比较简单。
（1）首先我们可以删除前面的CallRecord，callchargeRull等类，因为用不上了，然后照着第而题加上电信计费方式。
（2）写好那三种计费方式，修改删除好其他类后，在写主函数。
（3）先将正则表达式写出，本题一共要写两个。
String s1 = "u-1\\d{10}\\s3";
String s2 = "m-1\\d{10}\\s1\\d{10}\\s([a-z]|[A-Z]|[0-9]|[,]|[.]|[ ]){1,}";
（4）然后在主函数里分别写循环开户，匹配正则表达式；
在写1个if语句，判断1种计费方式。最后，使用foreach循环输出。
三、采坑心得：
1、正则表达式写错了导致无法匹配座机和手机号码：
*解决方法：
可以利用菜鸟工具写正则表达式方便，还可以跟着修改。
2、计算通信时间和打电话的时间错误：
SimpleDateFormat sdf3 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss"); try { starttime = sdf3.parse(stime); } catch (ParseException e2) { e2.printStackTrace(); } try { endtime = sdf3.parse(etime); } catch (ParseException e1) { e1.printStackTrace(); }
*解决方法：
使用如图所示的SimpleDateFormat类进行计算时间和日期。
3、用户输出排序问题，就是用户进行输出时没有排序。
*解决方法：
使用treeMape集合，非常实用，开户，输出，排序等操作比较方便。
https://blog.csdn.net/walkerkalr/article/details/81217294
4、忘记没有开户不能输出，也不会报错。
*解决方法：
加上如下代码：
if(f[3].equals("0791")) { if(treeMap.get(f[0])!=null&&treeMap.size()!=0){ treeMap.get(f[0]).getUserRecords().addCallingInCityRecords(cal);} } else if(f[3].equals("0701")||f[3].equals("0790")||f[3].equals("0792")||f[3].equals("0793")||f[3].equals("0794")||f[3].equals("0795")||f[3].equals("0796")||f[3].equals("0797")||f[3].equals("0798")||f[3].equals("0799")) { if(treeMap.get(f[0])!=null&&treeMap.size()!=0){ treeMap.get(f[0]).getUserRecords().addCallingInProvinceRecords(cal);} } else { if(treeMap.get(f[0])!=null&&treeMap.size()!=0){ treeMap.get(f[0]).getUserRecords().addCallingInLandRecords(cal);} if(treeMap.get(f[2])!=null&&treeMap.size()!=0){ treeMap.get(f[2]).getUserRecords().addAnswerInLandRecords(cal); }
四、改进建议：
1.首先，我觉得可以将我的正则表达式分开写分别判断，而不是一口气写完，这样更不容易错，比如这两个代码
if(a.substring(0,11).matches("t-0(\\d){9,11}\\s0(\\d){9,11}")) if(a.substring(11,22).matches("u-1\\d{10}\\s1")) if(a.substring(11,22).matches(d{4}.\\d{1,2}.\\d{1,2}\\s\\d{2}:\\d{2}:\\d{2}\\s\\d{4}.\\d{1,2}.\\d{1,2}\\s\\d{2}:\\d{2}:\\d{2})
String s5 = "t-1(\\d){10}\\s0(\\d){2,3}\\s0\\d{9,11}\\s\\d{4}.\\d{1,2}.\\d{1,2}\\s\\d{2}:\\d{2}:\\d{2}\\s\\d{4}.\\d{1,2}.\\d{1,2}\\s\\d{2}:\\d{2}:\\d{2}" ;
2.我觉得最后一题通信可以进行改进，变得更简单。
五.总结：
*经过12-15周的学习，我认为我主要还是提升了主在各种数据的处理方面，对类和对象的理解，逻辑思维能力，考虑问题全面能力，类设计能力。
*说实话作业的时间是够写的，但是我感觉有一定难度，移动业务资费问题有一定难度，但是如果第一题写好了，后面就好写了，因为是迭代作业，但是我第二题没有满分；考察了我们对面向对象的思考了，还有集合框架，类设计的思考，不只是考察我们的基本写一些代码的问题了，更多的是考察我们对面向对象这一实质的思考与研究，利用数据的私有和不同类之间的关联，考虑问题的全面性，以及SOLID设计原则，以及状态模式，策略模式的应用。我以后一定要更加努力学习。
*希望老师能多多指导我们，讲一讲题目。最后，希望我们能顺利通过期末考试，取得一个好成绩。
