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

 

7-1 电信计费系列2-手机+座机计费

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:
1、针对市内座机用户采用的计费方式(与电信计费系列1内容相同):
月租20元,接电话免费,市内拨打电话0.1元/分钟,省内长途0.3元/分钟,国内长途拨打0.6元/分钟。不足一分钟按一分钟计。
假设本市的区号:0791,江西省内各地市区号包括:0790~0799以及0701。
2、针对手机用户采用实时计费方式:
月租15元,市内省内接电话均免费,市内拨打市内电话0.1元/分钟,市内拨打省内电话0.2元/分钟,市内拨打省外电话0.3元/分钟,省内漫游打电话0.3元/分钟,省外漫游接听0.3元/分钟,省外漫游拨打0.6元/分钟;
注:被叫电话属于市内、省内还是国内由被叫电话的接听地点区号决定,比如以下案例中,南昌市手机用户13307912264在区号为020的广州接听了电话,主叫号码应被计算为拨打了一个省外长途,同时,手机用户13307912264也要被计算省外接听漫游费:
u-13307912264 1
t-079186330022 13307912264 020 2022.1.3 10:00:25 2022.1.3 10:05:11

输入:
输入信息包括两种类型
1、逐行输入南昌市用户开户的信息,每行一个用户,含手机和座机用户
格式:u-号码 计费类型 (计费类型包括:0-座机 1-手机实时计费 2-手机A套餐)
例如:u-079186300001 0
座机号码由区号和电话号码拼接而成,电话号码包含7-8位数字,区号最高位是0。
手机号码由11位数字构成,最高位是1。
本题在电信计费系列1基础上增加类型1-手机实时计费。
手机设置0或者座机设置成1,此种错误可不做判断。
2、逐行输入本月某些用户的通讯信息,通讯信息格式:
座机呼叫座机:t-主叫号码 接听号码 起始时间 结束时间
t-079186330022 058686330022 2022.1.3 10:00:25 2022.1.3 10:05:11
以上四项内容之间以一个英文空格分隔,
时间必须符合"yyyy.MM.dd HH:mm:ss"格式。提示:使用SimpleDateFormat类。
输入格式增加手机接打电话以及收发短信的格式,手机接打电话的信息除了号码之外需要额外记录拨打/接听的地点的区号,比如:
座机打手机:
t-主叫号码 接听号码 接听地点区号 起始时间 结束时间
t-079186330022 13305862264 020 2022.1.3 10:00:25 2022.1.3 10:05:11
手机互打:
t-主叫号码 拨号地点 接听号码 接听地点区号 起始时间 结束时间
t-18907910010 0791 13305862264 0371 2022.1.3 10:00:25 2022.1.3 10:05:11

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:
根据输入的详细通讯信息,计算所有已开户的用户的当月费用(精确到小数点后2位,单位元)。假设每个用户初始余额是100元。
每条通讯、短信信息均单独计费后累加,不是将所有信息累计后统一计费。
格式:号码+英文空格符+总的话费+英文空格符+余额
每个用户一行,用户之间按号码字符从小到大排序。
错误处理:
输入数据中出现的不符合格式要求的行一律忽略。

输入样例:

在这里给出一组输入。例如:

u-13811111111 1
t-13811111111 0791 13811111110 020 2022.1.3 08:00:00 2022.1.3 08:09:20
end

    public void setAnswerAddressAreaCode(String answerAddressAreaCode) {
        if(answerAddressAreaCode.matches("0791"))
        this.answerAddressAreaCode = "NC";
        else if(answerAddressAreaCode.matches("(079[0-9]|0701)")){
            this.answerAddressAreaCode = "JX";
        }else {

        return false;

abstract class CallChargeRule extends ChargeRule{
    
    public double calCost(ArrayList<CallRecord> callRecords) {
        return 0;
    }
    
}

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。
