一、前言
电信计费系列考察了类图的设计与关联，如继承，同时考察了抽象类的创建与使用及正则表达式的使用。题量适中，难度适中。
1. 电信计费系列 1-座机计费
作为第一次作业，本次座机计费为接下来的两次作业搭好框架，大多数类的设计都在此次作用中，如包括属性： userRecords （用户记录）、balance（余额）、chargeMode（计费方式）、number（号码）的User类，计费方式的抽象类ChargeMode，保存用户各种通话的记录的用户记录类UserRecords。抽象的通讯记录类CommunicationRecord，通话记录类CallRecord、短信记录类MessageRecord是它的子类。计费方式所包含的各种计费规则的集合的抽象类为chargeRules，计费方式所包含的各种计费规则类为callRecords， 座机拨打市内、省内、省外电话的计费规则类LandPhoneInCityRule、LandPhoneInProvinceRule、LandPhoneInLandRule三个类分别是其子类，用于实现这三种情况的费用计算。
2.电信计费系列 2-手机+座机计费
第二次作业建立在第一次基础上，新加入手机拨号。
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，如，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。
3.电信计费系列 3-短信计费
第三次作业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。

三、采坑心得
1.第一次作业对类的设计起初有些找不到头绪，好在题目所给出类图有参考价值，进而完成类图的设计与关联关系。
2.第二次作业新加了手机通话功能，对于数据的处理要求增加，是对于逻辑的缜密与清晰的一次考察。
3.第三次作业对于数据的顺序处理存在不熟练之处。
四、改进建议
1.作业一关于正则表达式半段年月日中的日期还存在漏洞，不能很好地区分错误测试样例，导致程序不完善进而丢分。
2.作业二存在的问题与第一次大同小异，对与数据的处理还有提高改进的空间。
3.作业三对数据的排序功能有待提高改进，对于
public int compareTo(User u) {
return this.number.compareTo(u.number);
}
的使用需要再加强
五、总结
有痛失分数的懊悔，也有巨大的收获。这三次作业让我对Java的继承关系 、实现关系、依赖关系 、关联关系、聚合关系、组合关系有了更进一步的认识。所以，通过这几次pta作业，所反映的问题首先就是需要熟悉类与类间的关系从而设计和使用，同时熟练的在各种情况下正确运用正则表达式，然后最最重要的不断学习，不断补充自己的过程，知识的更新日新月异，我们不仅要掌握一门知识，同时要掌握学习一门知识过程中所学到的方法，这样对于新知识的迁移与精进是很有帮助的。
