1.前言
在最近的几次pta作业中难度开始有了显著的提升，已经开始让我们做一些有技术要求的小项目。代码要求也比较复杂，用上了链表，多态，等知识点。
2.设计与分析
题目一
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。 假设本市的区号：0791，江西省内各地市区号包括：0790~0799以及0701。 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。 本题只考虑计费类型0-座机计费，系列2、3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。

第二题
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。

第三题
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。

三、踩坑心得：
这三周，我们写这个pta其中修复了很多bug，比如少写了添加的信息，导致有些东西传不进去或者报错，还有时候没有建立座机类导致一直会报错，有时候没有新建类导致有的信息没传，导致我会一直报错，就算我写完了都还有梳理很长时间的思路，当然这次的pta的作业让我知道了如何面向对象去设计实验，面向对象的好处，他的思路更清晰，修改起来更简单，代码耦合度小，代码复杂度低的优点。当我掌握这种方法后可以使代码复用度更高，可以使后面需要加什么代码直接可以加上去，不用再去另外写新的代码了。
四、改进建议：
这次的Main函数的代码太过于长了，导致很不好寻找，思路不清晰，耦合度有点高。
五、总结：
半年的学习java也结束了对自己的表现不是很满意。
对于自己写的程序来说bug还是有很多的，但形成的原因也是有很多的，比如类的混乱，还有随机数的产生导致有些点可以过，但随机数可能使那些点不能过。还有那些正则表达式超级长，看到就脑阔疼，今后我个人会尽量避免写出这样的代码，除非真的万不得已。
当然在写第五次大作业的时候7-1中的第3次情况写了一大段，但是当运行的时候就不能运行，一开始以为时是单纯的进不了循环，当测试几个样例的时候发现可以进入，那个时候就快崩溃了，当时代码写的太杂了，而且都是很混乱的，导致自己根本改不好，只能无奈的全删了，去骗分。当时就后悔了，应该讲那些代码写进一个类，在类里面进行判断，这样代码既不会写错，到时候改的时候也会更清晰明了一点。不会像这样气急败坏的删除了。
面向对象不一定比面向过程，面向结果优越，但是优秀的封装和类一定好太多了，第三次作业能写满分，我相信他的封装和代码一定比别人更清晰明了，也更容易看的懂。
展望：
经过这三个周的洗礼，我觉得我的代码能力有明显的提升，当然有些地方也有些不足，同时自我学习能力也会更强，因为那些正则表达式是自己在网络上找的资料学习的，当然大家的进步速度也是迅猛的，我也要加把劲。
在后面两次作业中，能明显感受到代码量增加，期中全部加起来都没有400行，但是第四五次大作业，一个题目就会有1000多行代码，因为里面包含很多算法和方法。
期望：
在这三周我学到了很多东西，例如一些函数的运用，同时也吸取了教训，积累了经验。
