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。
设计与分析

实现南昌市电信分公司的计费程序，假设该公司针对手机和座机用户分别采取了两种计费方案，分别如下： 输入： 注意：以上两类信息，先输入所有开户信息，再输入所有通讯信息，最后一行以“end”结束。 输出： |
输入样例:在这里给出一组输入。例如： |
输出样例:在这里给出相应的输出。例如： |

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。

一、实验目的 1、了解JavaFX的基本原理和基本组件； 2、能够熟练应用JavaFX组件进行界面设计； 3、掌握Java的事件驱动机制、lambda表达式； 4、掌握shape形状类的使用。 |

一、实验步骤 1、 请修改实验四农夫过河游戏的代码，将用户界面改为图形界面，界面效果自行设计。 2、 请画出修改后的类图，并说明在界面中使用了哪些技巧以达到较好地界面效果。 3、 途中遇见了图片无法加载的问题图3-1，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。 4、 类图见代码末尾。图1-1 |
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。
