10-16周作业总结

一．     前言

截至目前，这个学期的Java课程不知不觉的接近了尾声。在第10-16周的作业中主要的大作业是短信计费为主的，其中穿插着温习面向对象语言一些特性的习题。大作业相对于前几次的大作业，侧重点有所改变，从倾向数学算法向着重设计类之间的关联性进行了一个过度。总体来说是相对简单了些许，但是还会有些难度，难关从数学算法转换到了对于类之间的关联问题。例如：如何合理的利用抽象类，接口等一些相关的概念来使你的代码的逻辑性和可拓展性更高。

二．   设计与分析

对于此题，我的思路是按照老师的建议类图来创建相关类，在主函数中先是创建了5个String类型，1个自定义类User类型，1个自定义类CallRecord类型的容器用来保存接下来的数据。然后调用Scanner类并创建对象来获取用户从键盘上输入的全部数据，并存入第一个String类型的容器中去。之后再用正则表达式u-(0[0-9]{9,11}|1[0-9]{10}) [01]来对第一个String类型的容器的数据进行提取号码有效数据保存到第二个String类型的容器。之后String time = "[0-9]{4}\\.(([1-9])|(1[0-2]))\\.(([1-9])|((1|2)[0-9])|30|31) (((0|1)[0-9])|(2[0-3])):([0-5][0-9]):([0-5][0-9])"; String LandPhoneNumber = "[0-9]{7,8}";，两项正则表达式来对第一个String类型的容器的数据进行一个拨号信息的有效提取，最后得到有效数据存入到User类和CallRecord类容器中去。在对其进行相关匹配。得到一个个完全体数据结构，传入的相应的函数进行计算求和。在对求和类中利用到了Data类型的运算，来计算出拨打电话的时间。随后一个个的计算出各条数据所对应的费用，最后在进行相加。

 

对于此题我认为除去对类的一个全体的把控，正则表达式也是一个比较难把握的一个点。需要对其进行一个数据测试来验证是否真的可以剔除无效数据。

 

通过此题让我充分了解到Data数据类型实现了从一无所知到熟悉了它的具体用法

        {
            //System.out.println(U.get(o).number);
            System.out.println(U.get(o).number + " " +  U.get(o).calCost() + " " + U.get(o).calBalance());
        }
    }
}

 

 此题是对于上一题的一个拓展，这就体现了优质代码的可拓展性。相对于上一题，修改了计算相关类的一些判定，用来判断座机拨打电话与手机拨打电话。在主函数中额外添加正则表达式String LandPhoneNumber = "[0-9]{7,8}";

        String code = "0[0-9]{2,3}";

来判定拨打电话数据的格式是否正确。

还是正则表达式的问题，再此题中需要判断手机的格式和手机拨打座机，手机拨打手机，座机拨打手机等。需要大量的数据测试。

对于这题让我充分意识到了好的代码是具有优良的可拓展性，虽然开始构建框架是比较难的，但是在此基础上拓展的时候就体现了类的设计优良的优点了

这题虽是大作业最后一题，但是和前面几次的关联性就没有第一次和第二次那么强了。需要重新来设计架构来，不过架构简单了许多。只需注意短信发送的格式。而不用再刻意的管理座机了。在主函数中在录入完数据时候，要对发送短信的格式进行一个判断。我的思路是先进行一个大致的总体判断，没有可以去管理信息格式的判断。接着就专门提取信息数据利用阿斯克码值来判断数据是否是非法的。

对于此题的判断方式我写的有一些多余了，本可以一次判断格式，而我没有想到一个正则表达的写法，就拆成两次检查了。

给我启示就是正则表达式还需要再深入学习，以确保可以想匹配什么数据就匹配什么数据。

三.    踩坑心得

 在经历了短信计费系列作业后，我深刻意识到了自己正则表示上的不足，类结构设计的思想缺陷以及抽象类，接口的具体实现方法的不熟练。还需看慕课并且多加练习。

四．   改进意见

对题目集6   7-1题，题目集7    7-1，题目集8  7-1我的改进目标是编写代码是要严格按照类去定义其的属性和方法，让他们各司其职，并且又会有分工合作。

五．   总结

通过通讯计费作业，我又一次地认识到类的设计结构是多么的重要，如何合理的利用接口等一系列具体的方法。到后面的思考可以更加的符合面向对象语言的设计思路。
