最后三次大作业的总结Blog

------------恢复内容开始------------

1.前言

本次博客中，我将对座机，手机计费问题进行分析。这几次的大作业可以分为三个阶段。第一个阶段：座机计费。第二个阶段：手机与座机计费。第三个阶段：短信计费。总的来说，第二次大作业是最难的，第一次大作业作为开头也不简单，而第三次作业承接了前两次大作业的代码，故更为简单。因此，我将花费较大的篇幅对前两次大作业进行分析。

2.设计与分析

2.1 第一次大作业

在第一次大作业中，我们需要注意的是格式问题，尤其是时间的格式。直接进行判断不是一个明智额选择，因此，依题意，我们采用SimpleDateFormate方法来判断。同时，时间的计算也是一个难点。为此，我是用的是Data类中的Time方法。在判断完格式，计算完时间后，我们就需要对其进行计算。我们不难发现，座机计费的依据是接通座机的区号，与呼叫座机的区号无关，因此，我们仅需要判断接通座机的所在地。座机的区号包含在座机号码内部。在判断完地点后，我们就需要将各个通话记录存进各个ArrayList数组内部。

代码如下：

2.2 第二次大作业

第二次大作业在第一次大作业的基础上添加了手机计费。手机计费与座机计费不同，需要同时判断呼叫手机与接听手机的区号，同时不仅需要计算呼叫手机呼叫时产生的花费，还需要计算接听手机接听时产生的花费。与第一次类是，我们需要将每条通话记录的两个区号与号码提取出来后加入CallRecord数组中。与座机不同，手机的区号是不包括在手机号码内部的，而是跟在手机号码后的一串数字。

总的来说，我们可以将接听电话分为五大类：1：市内打市内。2：市内打省内。3：市内打省外。4：省内打全国。5：省外打全国。

而接听电话也可以分为两类：1：市内，省内接听电话。2：省外接听电话。

通话记录也可以分为四类：1：座机打座机。2：座机打手机。3：手机打座机。4：手机打手机。

每个开户号码既可能是呼叫号码，也可能是接听号码，因此，我们需要一个循环来遍历每一个通话记录。而在遍历每一个通话记录时，我们需要对其判断两次，判断其是呼叫号码还是接听号码。再在每个判断下将通话记录存入相应的UserRecord内。在计算费用时，接听费用与呼叫费用需要写在两个类中。在需要时只调用一个计算类。

 3.踩坑心得

3.1：由于userrecord数组太多，在存储时需要看清每个数组的名称，不要写错了，一旦写错了，就很难发现。

3.2：这几次大作业计算都不难。难的是要理清各个类之间的关系以及输入与数组的关系。

3.3：在第一次大作业排序时，我用的是hashmap，但是这个排序有一个致命的问题，那就是当月租不同时，余额的计算会出现错误。

3.4：在确定号码的区号时，要特别注意区分手机与座机的区别。

3.5：在计算时间和划分短信个数时，要注意存余，如果余数不为0，则需要在余数上加一。

4.改进建议

我在计算手机，座机话费时，额外添加了较多的userrecord数组，虽然很清晰明了，但是不够简便，我希望能够简化代码

在计算费用时，我并没有使用chargeMode类，而是越过chargeMode类直接调用了charge类（计算费用），这样显然不符合设计原则。我希望可以将费用类放在一个类内。

5.总结

类图对代码的实现尤为重要。我们可以在编写代码前先实现类图，然后根据类图实现代码。同时我们在编写代码时需要考虑到未来的规划，比如添加新功能，实现新方法。因此我们的代码需要有足够的扩展性。
