前言 10-16周java学习总结

近几周PTA的作业以电信收费为主，考试内容涉及正则表达式，字符串的比较.输入.分割代码的复用性.面向对象设计，ArrayList的使用等等。题目量和难度都适中。

期末考试主要考察了对课本知识的运用，例如多态，继承，抽象类，抽象类ArrayList的用法等等.难度题量都适中。

同时实验五考察了javafx的应用。

本次作业难度较大，代码写的有点乱，首先用while循环确保循环输入，直到end退出程序，输入一条语句立刻进行判断，执行开户，或者记录操作，如果输入两个相同的号码，将取消开户，对于计费，使用的是记录操作，记录下后传入ArrayLis的用户中储存起来，最后用costcal函数进行计算，再返回结果并保留两位小数，在这之前使用comperto进行排序，再将用户的信息按顺序输出。中间过程比较繁杂，细节比较多，就不再一一赘述。类图如下。

途中遇见了图片无法加载的问题，经过寻找，发现图片路径输入有误，修改路径后，程序正常运行。

通过按顺序点击农夫带羊过河—农夫独自过河—农夫带狼过河—农夫带羊过河—农夫带白菜过河—农夫独自过河—农夫带羊过河后，程序执行完毕，最终得到结果如见代码末尾2-1，程序正常运行，输出结果正常，点击农夫独自过河，得到结果如2-2，程序正常运行，输出正常。

通过javafx的实验让我掌握了基本的图形界面程序，让非专业用户能够一目了然程序的操作。将算法和用户操作分开，让程序维护和修改更容易，减少以后代码的修改量。过程中遇到了图片为空，无法加载的问题，后来发现是因为路径搞错了，修改路径以后正常运行。

类图及相关运行界面如下。

踩坑心得：

实验中存在不少细节问题，例如狼先吃羊，故羊无法再吃白菜，白菜存活，故需判断当羊进食时是否活着等等问题。本题可将农夫，狼，羊，白菜的共有属性放入一个父类中，用船来执行过河的操作，降低代码的耦合度，提高代码的复用性，方便日后修改添加新类。途中遇见了图片无法加载的问题，经过寻找，发现图片路径输入有误，修改路径后，程序正常运行。

改进建议：

建议多提供输入样例，方便进行判断，修善代码，多出些和所学契合的题目。

总结：

学会了使用抽象类，抽象方法继承与多态，使用容器类，降低代码的耦合度，提高复用性。同时学会了流的运用，文件流的读入写出等等操作，学会了使用异常处理，声明，抛出，抓取异常，优雅的终止错误。对于以上学习内容，对于容器类应该进一步学习和研究熟练的使用ArrayList ， 学会了使用fx中的类，例如button等。希望老师能够提供答案或者上课讲一讲这些题目。
