饼干妹妹的第三次博客作业

一、三次作业的知识点、题量、难度

　考察的知识点

　　主要考察了对类的结构设计的理解，以及在处理输入时的方法。

　作业的题量与难度

　　三次题目集的内容感觉在熟悉了Java之后并不难，除了在思考类的结构设计时会有一点难度，在其他编码方面感觉没有什么困难。

二、设计与分析

　　①题目集7（7-1）与题目集7（7-2）两道题目的递进式设计分析总结：

　　　　我这里先把源码贴上来：

三、踩坑心得

　　这三次作业还是不难的，首次不踩坑，好耶！

四、总结

　　这三次题目集我是真切的感受到了Java的魅力，通过对类结构一系列的设计能简化许多很麻烦的操作，收获还是很大的，但是到现在的学习还是不够，对Java的理解还是不够透彻，多操作多实践多提问才能更好学习和研究。
