第三阶段Blog作业--题目集7~9的总结性Blog

好的，这是我第二次在博客这种大型网站上发布我对于java的认知和感悟，新手上路，请多关照，若有错误之处，望君谅解并指出。废话不多说，现在就总结一下题目集7~9的部分做过的题及遇到的困难及总结。

1. 题目集7（7-1）

1.这道题考察的是根据用户输入的数字和图形数据来创建不同图形对象并把不同图形的面积大小计算并进行比较得出结果并显示，因为涉及到图形对象的面积比较和用户输入需要创建的图形数未知的原因，故需创建 ArrayList<shape> arrayList 进行存储未知数量的图形对象，并利用比较器对其中创建图形对象的面积进行排序，然后对数据的输出格式进行调试，这道题唯一的难点就是图形比较器的创建，其余抽象类的继承和创建都很基础(三角形的面积公式之前有写)。

2.题目集7（7-2）

1.这道题是7-1的升级版，它在7-1的基础上增加了对各个图形类的统一输出，且在之后对各个图形类进行面积比较排序后输出，输出格式也比7-1的复杂一些，但这道题目的核心和7-1是一样的，我的做法是在7-1的基础上增加判断条件将各个图形类存储到逐一的ArrayList<shape> arrayList中，在进行排序后输出即可，在写这道题时输出格式中的[]的要求看错了花了一些时间。

3.题目集8（7-1）

1.这道题说到底就是搞清银行，账户，用户，ATM机，卡号之间的包含关系，经过一番思索，我设置了建行、工行两个银行类，它们包含各自的账户arraylist 和ATM arraylist，在账户arraylist中不但包含用户的姓名和其他基本信息，也包含了卡号arraylist，这些arraylist中卡号共用一个账户中的金额，基本的取款和存款方法放在银行类中，跨行的判断是先判断输入的卡号前5位的数字所属于哪类银行，再遍历该银行帐户列表中的ATM机列表，如果没有输入ATM机数字的匹配对象，再进行另一银行的ATM机列表匹配，若有则进行先相应的跨行服务，若无，输出错误。

4.题目集9（7-1）

1.这道题是题目集8的升级版，增加了农行，新的用户、跨行业务需要计算额外的百分比费用，另外还添加了透支业务，计算倒是没什么问题，但这个收取百分比的费用我有些不懂，我按照题目所说的百分比计算得出的结果和pta上的测试结果不一样，我很无奈，另外我写的程序也有一个问题，是取款后查询该账户余额它还是一万，我以为它没保存，但在多次取款中却没有这个问题，我不知道出现了什么问题，这道题没怎么写好。

（3）踩坑心得；就这三次题目集来说由于输入数据的数量较多，调用函数的次数较多，一旦出现错误很难发现

关于类的继承则要注意父类的编写，要注意其中父类方法与数据的类型，以防止子类在继承中的顺利使用。

（4）改进建议：我觉得这三次的题目的代码都具有比较大的可扩展性，但是我学的不多,还需要进一步扩展。

（5）总结：就这三次的题目集写下来，虽然有些题目的难度较大，但毕竟这是一个循序渐进的过程，到了后期题目难度明显的下降了，但我觉得我学到的东西也变多了，慢慢的了解了JAVA的运作方式，用对象来完成工作，因此重要之处就在于如何编写类，类的结构因该要如何。总的来说我要学的东西还有许多。
