题目集7~9总结

1.前言

　　①题目集07：共有两题，两题难易度差不多。其中第一题为图形卡片排序游戏，其中该题主要运用了继承多态等方面的只是，还运用到了Comparable 接口的应用，知识点属于较难的，且有些是第一次使用，这题与之前的图形题目加了排序功能，比较新颖。第二题为图形卡片分组游戏，该题也是运用了继承多态方面的知识和Comparable、Comparator 接口的应用，这一题和上一题相比，需要为图形卡片分组，难度也没有提升多少，就是思路需要有些改变。这两题继承和接口两方面的知识起到了很大的作用。

　　②题目集08：只有一题，但这题与前面所有的题目集相比，难度可以说是最大的，代码也是最繁琐的。该题要求编写一个银行 ATM 机的模拟程序，能够完成用户的存款、取款以及查询余额功能。其中银行，用户，ATM机都初始化了。并且这题运用的知识也非常广泛，占了这学期学的内容很大一部分。

　　③题目集09：只有一题，这题可以说是08题目集的升级版，这题为ATM机类结构设计（二），代码也比上一题繁琐一些。该题要求编写一个银行 ATM 机的模拟程序，能够完成用户的取款以及查询余额功能。并且相较于上一题，还多了一些功能。银行账户分为借记账户和贷记账户两种，其中，借记账户不能够透支取款，而贷记账户可以透支取款（可能需要支付手续费）。根据账户的不同，银行卡一般分为借记卡（针对借记账户）和信用卡（针对贷记账户）两类。这些要求大大加大了难度，运用的知识也不比上一题少。

3.采坑心得

　　这几个题目都运用了新知识，以及一些接口的使用，刚开始写这些也令我非常烦恼，但是后来发现，尽管这几个题目中两两相似，但是在编写的过程中发现还是很大不一样，所以思路不能太过于局限，要打开新思维，才能更好的改进代码。

4.改进建议

　　这里是我题目集08的代码，感觉还需要对其中的输出方式，以及ATM的存储进行改进。

public String getNumber() {
return number;
}

5.总结

　　这三次题目集是我对java的编写更加感兴趣，并且学习到了更多的知识，在编写代码的同时通过不断去翻阅资料，学习视频，掌握越来越多的知识，对代码的编写规则，编写规范上更是有了进一步的提升。老师在课堂上讲的东西也非常的有用，都是一些重点，老师的课教学的很有质量，最后感谢老师的教学，使得我对程序的编写更近一步！
