第四次题目集

7-1 菜单计价程序-4
分数 100
作者 蔡轲
单位 南昌航空大学
本体大部分内容与菜单计价程序-3相同,增加的部分用加粗文字进行了标注。

设计点菜计价程序,根据输入的信息,计算并输出总价格。

输入内容按先后顺序包括两部分:菜单、订单,最后以"end"结束。

菜单由一条或多条菜品记录组成,每条记录一行

每条菜品记录包含:菜名、基础价格 两个信息。

订单分:桌号标识、点菜记录和删除信息、代点菜信息。每一类信息都可包含一条或多条记录,每条记录一行或多行。

桌号标识独占一行,包含两个信息:桌号、时间。

桌号以下的所有记录都是本桌的记录,直至下一个桌号标识。

点菜记录包含:序号、菜名、份额、份数。份额可选项包括:1、2、3,分别代表小、中、大份。

不同份额菜价的计算方法:小份菜的价格=菜品的基础价格。中份菜的价格=菜品的基础价格1.5。小份菜的价格=菜品的基础价格2。如果计算出现小数,按四舍五入的规则进行处理。

删除记录格式:序号 delete

标识删除对应序号的那条点菜记录。

如果序号不对,输出"delete error"

代点菜信息包含:桌号 序号 菜品名称 份额 分数

代点菜是当前桌为另外一桌点菜,信息中的桌号是另一桌的桌号,带点菜的价格计算在当前这一桌。

程序最后按输入的桌号从小到大的顺序依次输出每一桌的总价(注意:由于有代点菜的功能,总价不一定等于当前桌上的菜的价格之和)。

每桌的总价等于那一桌所有菜的价格之和乘以折扣。如存在小数,按四舍五入规则计算,保留整数。

折扣的计算方法(注:以下时间段均按闭区间计算):

周一至周五营业时间与折扣:晚上(17:00-20:30)8折,周一至周五中午(10:30--14:30)6折,其余时间不营业。

周末全价,营业时间:9:30-21:30

如果下单时间不在营业范围内,输出"table " + t.tableNum + " out of opening hours"

参考以下类的模板进行设计(本内容与计价程序之前相同,其他类根据需要自行定义):

菜品类:对应菜谱上一道菜的信息。

Dish {

String name;//菜品名称

int unit_price; //单价

int getPrice(int portion)//计算菜品价格的方法,输入参数是点菜的份额(输入数据只能是1/2/3,代表小/中/大份) }

菜谱类:对应菜谱,包含饭店提供的所有菜的信息。

Menu {

Dish[] dishs ;//菜品数组,保存所有菜品信息

Dish searthDish(String dishName)//根据菜名在菜谱中查找菜品信息,返回Dish对象。

Dish addDish(String dishName,int unit_price)//添加一道菜品信息

}

点菜记录类:保存订单上的一道菜品记录

Record {

int orderNum;//序号

Dish d;//菜品\

int portion;//份额(1/2/3代表小/中/大份)

int getPrice()//计价,计算本条记录的价格

}

订单类:保存用户点的所有菜的信息。

Order {

Record[] records;//保存订单上每一道的记录

int getTotalPrice()//计算订单的总价

Record addARecord(int orderNum,String dishName,int portion,int num)//添加一条菜品信息到订单中。

delARecordByOrderNum(int orderNum)//根据序号删除一条记录

findRecordByNum(int orderNum)//根据序号查找一条记录

}

本次课题比菜单计价系列-3增加的异常情况:

1、菜谱信息与订单信息混合,应忽略夹在订单信息中的菜谱信息。输出:"invalid dish"

2、桌号所带时间格式合法(格式见输入格式部分说明,其中年必须是4位数字,月、日、时、分、秒可以是1位或2位数),数据非法,比如:2023/15/16 ,输出桌号+" date error"

3、同一桌菜名、份额相同的点菜记录要合并成一条进行计算,否则可能会出现四舍五入的误差。

4、重复删除,重复的删除记录输出"deduplication :"+序号。

5、代点菜时,桌号不存在,输出"Table number :"+被点菜桌号+" does not exist";本次作业不考虑两桌记录时间不匹配的情况。

6、菜谱信息中出现重复的菜品名,以最后一条记录为准。

7、如果有重复的桌号信息,如果两条信息的时间不在同一时间段,(时段的认定:周一到周五的中午或晚上是同一时段,或者周末时间间隔1小时(不含一小时整,精确到秒)以内算统一时段),此时输出结果按不同的记录分别计价。

8、重复的桌号信息如果两条信息的时间在同一时间段,此时输出结果时合并点菜记录统一计价。前提:两个的桌号信息的时间都在有效时间段以内。计算每一桌总价要先合并符合本条件的饭桌的点菜记录,统一计价输出。

9、份额超出范围(1、2、3)输出:序号+" portion out of range "+份额,份额不能超过1位,否则为非法格式,参照第13条输出。

10、份数超出范围,每桌不超过15份,超出范围输出:序号+" num out of range "+份数。份数必须为数值,最高位不能为0,否则按非法格式参照第16条输出。

11、桌号超出范围[1,55]。输出:桌号 +" table num out of range",桌号必须为1位或多位数值,最高位不能为0,否则按非法格式参照第16条输出。

12、菜谱信息中菜价超出范围(区间(0,300)),输出:菜品名+" price out of range "+价格,菜价必须为数值,最高位不能为0,否则按非法格式参照第16条输出。

13、时间输入有效但超出范围[2022.1.1-2023.12.31],输出:"not a valid time period"

14、一条点菜记录中若格式正确,但数据出现问题,如:菜名不存在、份额超出范围、份数超出范围,按记录中从左到右的次序优先级由高到低,输出时只提示优先级最高的那个错误。

15、每桌的点菜记录的序号必须按从小到大的顺序排列(可以不连续,也可以不从1开始),未按序排列序号的输出:"record serial number sequence error"。当前记录忽略。(代点菜信息的序号除外)

16、所有记录其它非法格式输入,统一输出"wrong format"

17、如果记录以“table”开头,对应记录的格式或者数据不符合桌号的要求,那一桌下面定义的所有信息无论正确或错误均忽略,不做处理。如果记录不是以“table”开头,比如“tab le 55 2023/3/2 12/00/00”,该条记录认为是错误记录,后面所有的信息并入上一桌一起计算。

本次作业比菜单计价系列-3增加的功能:

菜单输入时增加特色菜,特色菜的输入格式:菜品名+英文空格+基础价格+"T"

例如:麻婆豆腐 9 T

菜价的计算方法:

周一至周五 7折, 周末全价。

注意:不同的四舍五入顺序可能会造成误差,请按以下步骤累计一桌菜的菜价:

计算每条记录的菜价:将每份菜的单价按份额进行四舍五入运算后,乘以份数计算多份的价格,然后乘以折扣,再进行四舍五入,得到本条记录的最终支付价格。

最后将所有记录的菜价累加得到整桌菜的价格。

输入格式:

 


 

桌号标识格式:table + 序号 +英文空格+ 日期(格式:YYYY/MM/DD)+英文空格+ 时间(24小时制格式: HH/MM/SS)

菜品记录格式:

菜名+英文空格+基础价格

如果有多条相同的菜名的记录,菜品的基础价格以最后一条记录为准。

点菜记录格式:序号+英文空格+菜名+英文空格+份额+英文空格+份数注:份额可输入(1/2/3), 1代表小份,2代表中份,3代表大份。

删除记录格式:序号 +英文空格+delete

代点菜信息包含:桌号+英文空格+序号+英文空格+菜品名称+英文空格+份额+英文空格+分数

最后一条记录以“end”结束。

输出格式:

 


 

1、桌号,格式:table+英文空格+桌号+”:”+英文空格

2、按顺序输出当前这一桌每条订单记录的处理信息,

每条点菜记录输出:序号+英文空格+菜名+英文空格+价格。其中的价格等于对应记录的菜品*份数,序号是之前输入的订单记录的序号。如果订单中包含不能识别的菜名,则输出“** does not exist”,**是不能识别的菜名

如果删除记录的序号不存在,则输出“delete error”

最后按输入顺序一次输出每一桌所有菜品的总价(整数数值)格式:table+英文空格+桌号+“:”+英文空格+当前桌的原始总价+英文空格+当前桌的计算折扣后总价

思路分析:

先题目很长,需要仔细阅读,挺考验人的耐心的,但是只要将题目分析提取,其实大致的思路就已经出来了。分好类就可以开始敲代码了。类图如下:

 

 

 

 

然后呢分好类之后,就要根据不同的部分进行相应的操作,输入菜谱这块的话,需要先用split方法将字符串以空格分隔,然后将分好的存进一个数组当中,接着把菜名和菜价存进已经new好的dish数组当中,这就是菜谱的存储方法,接着就是像订单啊之类的操作。其实和这个都有所相似,细节不同而已。
然后将代点菜的操作完成之后,删除的代码也补上,就到了最后的计算总价的环节了,这里要注意时间不同打的折扣也不同,所以还要进行四舍五入的操作,然后根据tables数组的顺序,依次输出每桌的折扣前的价格和折扣后的价格,就大功告成了。

分析:

这一题的输入方面的处理其实和菜单计价4没什么太大的差距,都是使用正则表达式来控制区分输入的是哪一种处理,但是菜单计价5多了一个新的功能,就是增加了川菜浙菜等菜系的特色,在菜单的增加方面,其实和菜单4是一样的,只不过我加了一个record的新属性,就是flag,我把普通菜的glag当作0,而特色菜分别flag为1,2,3,这样我认为是不改变源代码的最为简便的方法了。

 

 

类图如下:

 

 

可以从类图看出,此题我使用了除了Main类的七个类,分别是record类,Dish类,Panduan类,Menu类和Table类,Rt类及Kouwd类用来判断口味度,因为是对菜单3的拓展,与菜单4不同的是,在菜单5里,增加了计算不同菜系口味度的方面的要求,其他在价格的计算上与第一题无差别,仍然是不同的时间对应不同的折扣。

 

 

 

期中考试

7-1 测验1-圆类设计

这题没什么难度,很基础。

 

7-2 测验2-类结构设计

设计一个矩形类,其属性由矩形左上角坐标点(x1y1)及右下角坐标点(x2y2)组成,其中,坐标点属性包括该坐标点的X轴及Y轴的坐标值(实型数),求得该矩形的面积。

分析:这题原题给了类图,难度也不大,直接根据类图去设计代码即可。

 

7-3 测验3-继承与多态

将测验1与测验2的类设计进行合并设计,抽象出Shape父类(抽象类),CircleRectangle作为子类,类图如下所示:

 

分析:这题其实就只是在第一题和第二题的基础上添加一个父类,第一题第二题只要写出来了,那第三题其实也大差不差了。

 

7-4 测验4-抽象类与接口

第四题没写出来。。。。。。
