前言
本次作业知识点:类与对象的复杂使用，继承的进阶使用，各种接口的实现，还主要考察了正则表达式的运用，字符串的提取分割；
个人体会:本次作业难度适中，题量适中，但有些比较复杂的类设计上容易出现错误；第六次作业未给出测试点，自行测试使作业难度增加，测试时间增多

设计与分析
第四次作业
答题判题程序-4
第四次作业中的类比较，结构较为复杂，类间关系复杂，新加入多选题和填空题两种类，不同题目类可以继承同一个父类；
第五次作业
家居电路模拟程序-1
本次作业是家居电路模拟程序第一次作业，类间关系较为简单，主要为不同电器类与控制设备类继承同一个父类；
第六次作业
家居电路模拟系统-2
本次作业新加入了落地扇类、串联电路与并联电路类，落地扇继承电子设备类，串联电路与并联电路中有不同电器类，两种不同电路类中还有另一个电路类，类间关系更难设计；
踩坑心得
第四次作业
答题判题程序-4
本次作业中出现较多问题，对格式的处理，以及多学生多试卷容易出现非零返回等问题，主要由于各种循环处理不当，信息输出顺序出现问题，导致各种问题出现；
第五次作业
家居电路模拟程序-1
本次作业为家居电路第一次作业，作业难度较为简单，问题主要是对各种设备的输出处理，以及各种设备的输出顺序还有最后一个不回车处理，以及多个开关等情况；
第六次作业
家居电路模拟系统-2
本次作业较上一次有所提高，问题主要出现在计算，对并联电路上多个电器存在时忘记进行分压处理，以及忘记将新添加的落地扇电器进行处理，导致出现问题；
改进建议
- 对接口的使用较少，后续比较等可使用Comparable接口代替比较方法
- 未使用抽象类，对抽象类理解不足
- 对引脚的处理后续可使用Hash Map来储存一个设备的不同引脚
- 父类中有很多一些子类不使用的属性，浪费储存空间
- 注释过少，后续代码可通过添加注释令代码简单易懂
- 对强制转换的使用不够熟练，使用父类时调用父类数据而未调用子类数据
总结
在本次系列作业中，我们经历了从简单的类结构设计到复杂的类间关系构建的过程，通过答题判题程序、家居电路模拟程序等任务，不仅加深了对面向对象编程的理解，也认识到了在实际编程中可能遇到的挑战和问题。
通过这三次作业，我们深刻体会到了面向对象编程中的种种挑战。从循环处理不当、输出顺序错误，到电路计算中的疏忽，每一次问题都让我们对编程的严谨性有了更深的认识。同时，也让我们意识到在编程过程中，不仅要关注代码的逻辑正确性，还要关注代码的可读性和可维护性。
经过连续三次的作业挑战，我对于面向对象编程的理解和应用能力有了显著提升。从答题判题程序到家居电路模拟系统，每一次的作业都加深了我对类设计、继承、多态等核心概念的理解。
