JAVA PTA 第三次大作业
（1）前言：
这几次的大作业还是比较简单的，只需要按照题目给出的类图，对应的写出相应的类，框架已经给出，你只需要填充就行了，多看几遍题目的类图，理清类之间的关联差不多就能写出了。
题量也不是太多，快的话就一天的事(指的是写一天的代码)。
知识点涉及到继承，多态，SimpleDateFormat类。
（2）设计与分析：
7-1 电信计费系列1-座机计费
作者 蔡轲
单位 南昌航空大学
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。

类图：
SourceMonitor生成报表：
一 . 首先是对输入进行检测。
1.用户检测
boolean UserLegal(){ String [] ss= s.split(" "); if(ss.length!=2) return false; String legal= "u-(0701|079\\d){1}\\d{7,8}[\\ ][0-2]"; return s.matches(legal); }
2.用户记录检测
boolean RecordLegal() throws ParseException { String[] ss = s.split(" "); if(ss.length!=6) return false; String legal = "[t]-[0-9]{10,12}"; String legal1 = "\\d{10,12}"; String legal2 = "((2[0-3])|([0-1]?[0-9])):[0-5][0-9]:[0-5][0-9]"; return ss[0].matches( legal ) && ss[1].matches(legal1) && checktime(ss[2]) && checktime(ss[4]) && ss[3].matches(legal2) && ss[5].matches(legal2); }
public boolean checktime(String date) //检查年月日的合理性 { if(!date.matches("[1-9]\\d{3}\\.\\d{1,2}\\.\\d{1,2}")) return false; if(!date.matches("\\d{4}\\.(\\d|[1-9]\\d)\\.(\\d|[1-9]\\d)")) return false; String[] num = date.split("\\."); int year = Integer.parseInt(num[0]); int month = Integer.parseInt(num[1]); int day = Integer.parseInt(num[2]); if(month<1||month>12) return false; if(day<1) return false; int[] months={0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 }; if((year%400==0)||(year%4==0&&year%100!=0)) { months[2]++; } return day <= months[month]; }
时间的检测也可以用SimpleDateFormat类进行检测。
boolean isLegalDate(String s){ if(!s.matches("[1-9]\\d{3}\\.\\d{1,2}\\.\\d{1,2}")) return false; if(!s.matches("\\d{4}\\.(\\d|[1-9]\\d)\\.(\\d|[1-9]\\d)")) return false; boolean judgeresult=true; //1、首先使用SimpleDateFormat初步进行判断，过滤掉注入 yyyy-01-32 或yyyy-00-0x等格式 //此处可根据实际需求进行调整，如需判断yyyy/MM/dd格式将参数改掉即可 SimpleDateFormat format = new SimpleDateFormat("yyyy.MM.dd"); try{ //增加强判断条件，否则 诸如2022-02-29也可判断出去 format.setLenient(false); Date date =format.parse(s); //System.out.println(date); }catch(Exception e){ judgeresult=false; } // //由于上述方法只能验证正常的日期格式，像诸如 0001-01-01、11-01-01，10001-01-01等无法校验，此处再添加校验年费是否合法 // String yearStr=s.split(".")[0]; // if(yearStr.startsWith("0")||yearStr.length()!=4){ // judgeresult=false; // } return judgeresult; }
3.还有一些对输入的处理
Date getstartTime() throws ParseException { SimpleDateFormat format = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss"); String[] ss = s.split(" "); String d1=ss[2]+" "+ss[3]; Date date1= format.parse(d1); return date1; } Date getendTime() throws ParseException { SimpleDateFormat format = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss"); String[] ss = s.split(" "); String d2 = ss[4]+" "+ss[5]; Date date2= format.parse(d2); return date2; } int calculate_minute() throws ParseException { SimpleDateFormat format = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss"); String[] ss = s.split(" "); String d1=ss[2]+" "+ss[3]; String d2 = ss[4]+" "+ss[5]; Date date1= format.parse(d1); Date date2= format.parse(d2); long from = date1.getTime(); long after= date2.getTime(); int miao = (int )((after-from)/1000); int fen = (int) Math.ceil(miao*1.0/60); return fen; } String getcalling(){ String[] ss = s.split(" "); return ss[0].substring(2); } String getanswer(){ String[] ss = s.split(" "); return ss[1]; } String getcallingAddressAreaCode(){ String tep= s.substring(2); String[] ss=tep.split(" "); if(ss[0].length()==10) return ss[0].substring(0,3); return ss[0].substring(0,4); } String getanswerAddressAreaCode(){ String[] ss = s.split(" "); if(ss[1].length()==10) return ss[1].substring(0,3); return ss[1].substring(0,4); }
二 . 进行数据处理
while(!s.equals("end")){ in= new Input(s); if(in.UserLegal()){ User tep= new User(); tep.setNumber(in.Usercheck()[0]); user.add(tep); ChargeMode chargeMode= new LandlinePhoneCharging(); chargeMode.chargeRules.add(new LandPhonelnCityRule()); chargeMode.chargeRules.add(new LandPhoneProvinceRule()); chargeMode.chargeRules.add(new LandPhonelnlandRule()); tep.serChargeMode(chargeMode); } else if(in.RecordLegal()){ callRecord= new CallRecord(in.getstartTime(),in.getendTime(),in.getcallingAddressAreaCode(),in.getanswerAddressAreaCode()); User tep =null; for(User a:user) if(a.getNumber().equals(in.getcalling())) tep= a; if(tep!=null){ if(judgechargemode(callRecord.getCallingAddressAreaCode(),callRecord.getAnswerAddressAreaCode())==0){ tep.userRecords.addcallinglnCityRecords(callRecord); } if(judgechargemode(callRecord.getCallingAddressAreaCode(),callRecord.getAnswerAddressAreaCode())==1){ tep.userRecords.addcallinglnPrivinceRecords(callRecord); } if(judgechargemode(callRecord.getCallingAddressAreaCode(),callRecord.getAnswerAddressAreaCode())==2){ tep.userRecords.addcallinlnLandRecords(callRecord); }} } s= sc.nextLine(); }
三 . 计算金额
public double calCost(UserRecords userRecords){ double sum=0; for(ChargeRule a:chargeRules){ sum+=a.calCost(userRecords); } return sum; }
在每个计费规则中都有相应的计算 在这就放市内的
public double calCost(UserRecords records){ double sum =0; for(CallRecord a:records.callinglnCityRecords) if(calculate_minute(a.getStartTime(),a.getEndTime())>=0) sum+=calculate_minute(a.getStartTime(),a.getEndTime()); return (sum*0.1); }
public static int calculate_minute(Date d1, Date d2){ long from = d1.getTime(); long after= d2.getTime(); int miao = (int )((after-from)/1000); int fen = (int) Math.ceil(miao*1.0/60); return fen; }
四 .输出数据结果
public static void outans(ArrayList<User> user){ user= Coincident(user);//去重 java.util.Collections.sort(user);//排序 for (User a :user) System.out.printf("%s %.1f %.1f\n",a.number,a.chargeMode.calCost(a.userRecords),a.balance-a.chargeMode.getMonthlyRent()-a.chargeMode.calCost(a.userRecords)); }
7-1 电信计费系列2-手机+座机计费
分数 80
作者 蔡轲
单位 南昌航空大学
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

题目分析
这次的和上次的差不多就是多加了手机号的判断。
1.用户检测
要注意的是手机号的第二位只能在3-9之间(特地搜到的)，这里有一个测试点。
boolean UserLegal(){ String [] ss= s.split(" "); if(ss.length!=2) return false; String legal= "u-(0701|079\\d){1}\\d{7,8}[\\ ][0-3]"; return s.matches(legal); } boolean PhoneNumberLegal(){ String [] ss= s.split(" "); if(ss.length!=2) return false; String legal= "u-1[3-9][\\d]{9}[\\ ][0-3]"; return s.matches(legal); }
2.用户记录检测
有手机号和座机号的时候有两种情况，我这用一个flag来标记来区分，时间的检测和上次是一样的。
boolean RecordLegal() throws ParseException { String[] ss = s.split(" "); //if(ss.length!=6) return false; String PhoneLegal= "1[3-9][\\d]{9}"; String AddressAreaCode = "[0]([\\d]{2}|[\\d]{3})"; String legal = "0[\\d]{2,3}[\\d]{7,8}"; String legal2 = "((2[0-3])|([0-1]?[0-9])):[0-5][0-9]:[0-5][0-9]"; if(ss.length==6) return (ss[0].matches("[t]-"+legal) )&& (ss[1].matches(legal)) && checktime(ss[2]) && checktime(ss[4]) && ss[3].matches(legal2) && ss[5].matches(legal2); if(ss.length==7&&ss[0].matches("[t]-"+PhoneLegal)) { flag=2; return (ss[0].matches("[t]-" + PhoneLegal)) && (ss[1].matches(AddressAreaCode)) && ss[2].matches(legal) && checktime(ss[3]) && checktime(ss[5]) && ss[4].matches(legal2) && ss[6].matches(legal2); } else if(ss.length==7&&ss[0].matches("[t]-"+legal)) { flag= 1; return (ss[0].matches("[t]-" + legal)) && (ss[1].matches(PhoneLegal)) && ss[2].matches(AddressAreaCode) && checktime(ss[3]) && checktime(ss[5]) && ss[4].matches(legal2) && ss[6].matches(legal2); } if(ss.length==8) { return (ss[0].matches("[t]-" + PhoneLegal)) && (ss[1].matches(AddressAreaCode)) && ss[2].matches(PhoneLegal) && (ss[3].matches(AddressAreaCode)) && checktime(ss[4]) && checktime(ss[6]) && ss[5].matches(legal2) && ss[7].matches(legal2); } return false; }
3.输入的处理
有两种情况，要注意判断返回。
String getcalling(){ String[] ss = s.split(" "); return ss[0].substring(2); } String getRecord (){ String tep= s.substring(2); String[] ss=tep.split(" "); if(ss.length==8) return ss[2]; if(ss.length==7&&flag==2) return ss[2]; return ss[1]; } String getChageMode(){ String[] ss = s.split(" "); return ss[1]; } String getcallingAddressAreaCode(){ String tep= s.substring(2); String[] ss=tep.split(" "); if(ss.length==7&&flag==2){ return ss[1]; } if(ss.length==8){ return ss[1]; } if (ss[0].length() == 10) return ss[0].substring(0, 3); return ss[0].substring(0, 4); } String getanswerAddressAreaCode(){ String tep= s.substring(2); String[] ss=tep.split(" "); if(ss.length==7&&flag==1){ return ss[2]; } if(ss.length==7&&flag==2){ if(ss[2].length()==10) return ss[2].substring(0,3); return ss[2].substring(0,4); } if(ss.length==8){ return ss[3]; } if(ss[1].length()==10) return ss[1].substring(0,3); return ss[1].substring(0,4); } public static int judgechargemode(String s1,String s2){ return judgechargemodes1(s1)*10+judgechargemodes2(s2); } public static int judgechargemodes2(String s2){ String isprovince="(079[0-9]|0701)"; String iscity="0791"; if(s2.matches(iscity)) return 1; if(s2.matches(isprovince)) return 2; return 3; } public static int judgechargemodes1(String s1){ String isprovince="(079[0-9]|0701)"; String iscity="0791"; if(s1.matches(iscity)) return 1; if(s1.matches(isprovince)) return 2; return 3; } public static int calculate_minute(Date d1, Date d2){ long from = d1.getTime(); long after= d2.getTime(); int miao = (int )((after-from)/1000); int fen = (int) Math.ceil(miao*1.0/60); return fen; }
4.数据处理
手机接电话也要记录下来。
void LandlinePhone(ArrayList<User> user, CallRecord callRecord) throws ParseException { if(this.UserLegal()||this.PhoneNumberLegal()){ User tep= new User(); tep.setNumber(this.Usercheck()[0]); user.add(tep); ChargeMode chargeMode= new LandlinePhoneCharging(); chargeMode.chargeRules.add(new LandPhonelnCityRule()); chargeMode.chargeRules.add(new LandPhoneProvinceRule()); chargeMode.chargeRules.add(new LandPhonelnlandRule()); chargeMode.chargeRules.add(new SendMessgaeRule()); tep.serChargeMode(chargeMode); tep.chageMode = this.getChageMode(); } else if(this.RecordLegal()){ callRecord= new CallRecord(this.getstartTime(),this.getendTime(),this.getcallingAddressAreaCode(),this.getanswerAddressAreaCode()); User tep =null; User tep1 = null; user= User.Coincident(user); for(User a:user){ if(a.getNumber().equals(this.getcalling())) tep= a; if(a.getNumber().equals(this.getRecord())) tep1= a; } if(tep!=null) { //System.out.println(tep.number); if (judgechargemodes2(callRecord.getAnswerAddressAreaCode()) == 1) tep.userRecords.addcallinglnCityRecords(callRecord); if (judgechargemodes2(callRecord.getAnswerAddressAreaCode()) == 2) tep.userRecords.addcallinglnPrivinceRecords(callRecord); if (judgechargemodes2(callRecord.getAnswerAddressAreaCode()) == 3) tep.userRecords.addcallinlnLandRecords(callRecord); } if(tep1 != null){ if (judgechargemodes2(callRecord.getAnswerAddressAreaCode()) == 1) tep1.userRecords.addanswerlnCityRecords(callRecord); if (judgechargemodes2(callRecord.getAnswerAddressAreaCode()) == 2) tep1.userRecords.addanswerlnPrivinceRecords(callRecord); if (judgechargemodes2(callRecord.getAnswerAddressAreaCode()) == 3) tep1.userRecords.addanswerlnLandRecords(callRecord); } } else if(MessageLegal()){ String phone = s.substring(2,13); String messgae = s.substring(26); MessageRecord messageRecord = new MessageRecord(); messageRecord.setMessage(messgae); User tep =null; user= User.Coincident(user); for(User a:user){ if(a.getNumber().equals(phone)) tep= a; } if(tep!=null) { tep.userRecords.addsendMessageRecords(messageRecord); } } }
5.计算金额
市内的情况
public double calCost(UserRecords records,int n){ double sum =0,sum1=0,sum2=0,sum3=0; double money=0; if(n==0) { for (CallRecord a : records.callinglnCityRecords) sum += Main.calculate_minute(a.getStartTime(), a.getEndTime()); money= (sum * 0.1); } if(n==1){ for (CallRecord a : records.callinglnCityRecords){ if(Main.judgechargemodes1(a.getCallingAddressAreaCode())==1) sum1 += Main.calculate_minute(a.getStartTime(), a.getEndTime()); if(Main.judgechargemodes1(a.getCallingAddressAreaCode())==2) sum2 += Main.calculate_minute(a.getStartTime(), a.getEndTime()); if(Main.judgechargemodes1(a.getCallingAddressAreaCode())==3) sum3 += Main.calculate_minute(a.getStartTime(), a.getEndTime()); } money= (sum1 * 0.1)+sum2*0.3+sum3*0.6; } return money; }
省内的情况
public double calCost (UserRecords records,int n ){ double sum =0,sum1=0,sum2=0,sum3=0; double money = 0; if(n==0) { for (CallRecord a : records.callinglnPrivinceRecords) sum += Main.calculate_minute(a.getStartTime(), a.getEndTime()); money= (sum * 0.3); } if(n==1){ for (CallRecord a : records.callinglnPrivinceRecords){ if(Main.judgechargemodes1(a.getCallingAddressAreaCode())==1) sum1 += Main.calculate_minute(a.getStartTime(), a.getEndTime()); if(Main.judgechargemodes1(a.getCallingAddressAreaCode())==2) sum2 += Main.calculate_minute(a.getStartTime(), a.getEndTime()); if(Main.judgechargemodes1(a.getCallingAddressAreaCode())==3) sum3 += Main.calculate_minute(a.getStartTime(), a.getEndTime()); } money= (sum1 * 0.2)+sum2*0.3+sum3*0.6; } return money; }
省外的情况
public double calCost (UserRecords records,int n ){ double sum =0,sum1=0,sum2=0,sum3=0; double money=0; if(n==0) { for (CallRecord a : records.callinlnLandRecords) sum += Main.calculate_minute(a.getStartTime(), a.getEndTime()); money+= (sum * 0.6); } if(n==1){ for (CallRecord a : records.callinlnLandRecords){ if(Main.judgechargemodes1(a.getCallingAddressAreaCode())==1) sum1 += Main.calculate_minute(a.getStartTime(), a.getEndTime()); if(Main.judgechargemodes1(a.getCallingAddressAreaCode())==2) sum2 += Main.calculate_minute(a.getStartTime(), a.getEndTime()); if(Main.judgechargemodes1(a.getCallingAddressAreaCode())==3) sum3 += Main.calculate_minute(a.getStartTime(), a.getEndTime()); } for (CallRecord a : records.answerlnLandRecords){ sum += Main.calculate_minute(a.getStartTime(), a.getEndTime()); } money= (sum1 * 0.3)+sum2*0.3+sum3*0.6+sum*0.3; } return money; }
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）

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.
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。

题目分析
这题只需要写有关短信的，还是简单的，在前面加上短信计费方式，但不要将三次题目写在一起，会代码长度超出限制的。
计费代码
double calCost(UserRecords records, int n) { double sum =0; int w=0; if(n==3){ for(MessageRecord a:records.sendMessageRecords){ int num =(a.getMessage().length() + 10 - 1) / 10; w+=num; } if(w>3&&w<=5) sum+= (w-3)*0.2+0.3; else if(w>5) sum+= (w-5)*0.3+2*0.2+0.3; else sum+= w*0.1; } return sum; }
（3）采坑心得：
1. 在电信计费系列1-座机计费对于时间的检测不够严谨，比如月份以0开头，这个我调试了好久，呜呜呜。
加上
if(!date.matches("[1-9]\\d{3}\\.\\d{1,2}\\.\\d{1,2}")) return false; if(!date.matches("\\d{4}\\.(\\d|[1-9]\\d)\\.(\\d|[1-9]\\d)")) return false;
就行了。
2.Date的getTime()函数得到的是毫秒数，转化为秒的话需要除以1000。
3.电信计费系列3-短信计费中的短信内容 （短信内容只能由数字、字母、空格、英文逗号、英文句号组成），不能只判断字符的长度。
4.手机号的第二位在3-9之间。
5.还有要对用户先去重。
（4）改进建议：
对相应题目的编码改进给出自己的见解，做到可持续改进
这几次的大作业相较之前的大作业来说整体难度有所下降，类的设计也基本都是按着题目给的类图来设计，大家的代码都大同小异。
感觉可以写一个工厂类，在里面进行判断，返回相应的类。
（5）总结：
对本阶段（10-16周）综合性总结，学到了什么，哪些地方需要进一步学习及研究，对教师、课程、作业、实验、课上及课下组织方式等方面的改进建议及意见。
通过这几次大作业，我对面向对象编程的思想了解的更加深刻，对类图的获取信息，进行类图的改进，到最后的实现，都是一种练习。
这几次的大作业接近现实情况，我也是对输入不合法的情况进行了很多的判断，真的是百分之80的都是不合法的输入。
