Java-总结

这三次大作业相对于，前面的pta大作业算法上比较简单，但是后面三次大作业逻辑上比较难，但是经过后面三次的大作业的完成，知道了怎么面向对象，虽然要建立很多类，但是这样管理起来更方便，修改起来，或者添加功能也更加的方便，不用去大段的修改代码，也避免了大量的代码重复。同时，对于其他那些看代码的人也可以很好的看懂，也更直观。电信系列的大作业主要涉及了容器的知识，对信息的储存和便利，同时还考了容器内部排序，通过Collections函数进行排序，也通过对不同的用户进行不同的分类，放在不同的容器中。当然，其中也还涉及到子类、父类，分类，类的创建，类的管理，正则表达式等等。

　　难度相对于前几次的大作业来说，这三次的大作业难度还是相对比较低的，因为老师需要捞我们，所以pta的难度出的不大，但是前两次没有拿到满分，主要是正则表达式出问题了，但是一直找不到问题出现在哪里。

　　这三次大作业也涉及到了Data的应用，对于Data的应用对我来说当时是一片空白，但是我通过查找资料，来找到相应的方法。
