Motivation: The purpose of this project is to give students exposure to object-oriented design and programming using classes and polymorphism in an application that involves arrays of objects and sorting arrays containing objects. You will write several classes for this assignment. Please submit all classes in one file. The name of the physical program file submitted XXXX_Program8.java, where XXXX is your Kean email id. Assignment: Best Office Supplies Inc, an office supply store, services many customers. As customers' orders for office supplies are shipped, information is entered into a file. Best Office Supplies bills their customers once each month. At the end of each month, the Chief Executive Officer requests a report of all customers sorted by their customer id (from lowest to highest). The report includes their bill balance and tax liability. Write a program to produce the outstanding balance report sorted by customer ID number from the data in the text file. Below is a description of the information on the text file: ⚫ The first line on the file contains the number of customers on the file (numeric) - don't skip this The fields below repeat for each customer: 。 Customer name (String) 。 Customer ID (numeric integer) o Bill balance (numeric) Email Address (String) 。 Tax liability (numeric or String) The customers served by the office supply store are of two types: tax-exempt or non-tax-exempt. For a tax-exempt customer, the tax liability field on the file is the reason for the tax exemptions: education, non-profit, government, other (String). For a non-tax-exempt customer, the tax liability field is the percent of tax that the customer will pay (numeric) based on the state where the customer's business resides. Program requirements: From the information provided, write a solution that includes the following: • A suitable inheritance hierarchy which represents the customers serviced by the office supply company. It is up to you how to design the inheritance hierarchy. I suggest a Customer class and appropriate subclasses. . For all classes include the following: 。 Instance variables 。 Constructors 。 Accessor and mutator methods 。 Suitable toString() methods Any other appropriate methods Write a class XXXX_Program8.java which utilizes the following: o An Array(List) of Customer objects A method which reads the input file provided and stores the objects in the array of Customers. A method which sorts the array of Customers in ascending order by the customer ID. ⚫ A method that formats and prints the output report on a monitor. The report should include the following requirements: Report header at the start of each page showing the name of the company, report and page number. Report headers for each column of information. One Customer per line. ■ At most 20 Customers per page. ■ All money amounts and percentages should be displayed with 2 decimal places and commas after each thousand. • A sample report is shown at the end of the assignment. The report produced does not have to exactly match the sample output provided but must contain all required components listed above. 。 Any other helper methods used to meet the requirements of the assignment. The main method will call all the other methods which will: Read the text file and store the objects in the Array(List) . Sort the objects in ascending order by ID Format and print the report Office Supplies Inc Customer Report Page: 1 Kean Customer ====== == 1 ID Email Address ============= purchasing@kean.edu Balance ======= 158000.50 Тах Туре ======== education Tax Amount ========== Vassar 2 purchasing@vassar.edu 53000.00 education Google 3 purchasing@google.com 500.50 0.01 5.01 SetonHall 8 purchasing@setonhall.edu 158090.50 education JCU 9 purchasing@jcu.edu 135678.50 education Rutgers 10 purchasing@rutgers.edu 32000.00 education UPenn 11 purchasing@upenn.edu 350000.00 education CountyCollege1 12 purchasing@cc1.edu 5000.00 education LegoInc 18 purchasing@lego.com 1978.50 0.02 NYYankees 19 purchasing@nyyankees.com 15500.00 0.07 39.57 1085.00 NJIT 99 purchasing@NJIT.edu 13978.50 education Allied 100 purchasing@allied.com 85300.00 0.06 5118.00 TiresToGo 108 purchasing@tirestogo.com 8300.00 0.06 498.00 CountyCollege2 109 purchasing@cc2.edu 1678.50 education Fridays 110 purchasing@fridays.com 5300.00 0.06 318.00 Montclair 111 Linden 112 purchasing@montclair.edu purchasing@linden.gov 39800.00 education 3800.00 other Enterprise 120 purchasing@enterprise.com 75300.00 0.06 4518.00 ChocolateRus 125 purchasing@chocolate.com 3000.50 0.10 300.05 Beans 126 purchasing@beans.com 1000.50 0.03 30.02 Flowers Rus 339 Tires Inc 345 Uber 348 purchasing@flowers.com purchasing@tires.com purchasing@uber.com 59300.50 0.08 4744.04 25000.00 0.07 1750.00 1500.00 0.05 75.00 Office Supplies Inc Customer Report Page: 2 Customer ID Email Address Balance Тах Туре Tax Amount Threads 349 purchasing@threads.com DAV 358 purchasing@dav.org 29000.00 4860.20 0.05 non-profit 1450.00 DAV2 359 purchasing@dav2.org 4860.20 non-profit StopandShop 377 purchasing@stopandshop.com 8100.00 0.06 486.00 Alamo 520 purchasing@alamo.com 23000.00 0.05 1150.00 Hertz 521 purchasing@hertz.com 22200.00 0.07 1554.00 EnginesRus 522 BusinessRUS 531 purchasing@enginesrus.com purchasing@businessrus.com 23500.00 0.06 1410.00 1200.00 0.08 96.00 CareBear 535 purchasing@carebear.com 6000.00 0.08 480.00 PinkElephant 536 BabyGap 538 purchasing@pinkelephant.com purchasing@babygap.com 600.00 0.05 30.00 6100.00 0.07 427.00 Thrifty 539 purchasing@thrify.com 6600.00 0.07 462.00 BabyToys 539 DryCleaners CheapFood 540 purchasing@babytoys.com purchasing@drycleaners.com 6000.00 0.04 240.00 6800.00 0.05 340.00 551 purchasing@cheapfood.com 2210.00 0.04 88.40 Rubrics: Requirement % Possible % Earned Presence of instance variable in all created classes in proper format (naming conventions, correct data types, encapsulation) Presence of Constructors (a no-args constructor and a constructor that receives all possible parameters are a must) 5 5 Accessors and mutators should be implemented for all instance variables 5 toString() method is present in every class The main method calls all other methods (all three methods should be invoked by main()) Array(List) of Customers is created and utilized 5 10 5 Method to sort the array in ascending order by ID is present and implemented correctly 15 Method which reads text file (URL data) and stores objects in Array(List) of Customers 15 15 Method to print report in proper format (One customer per line, header, page break for every 20 Customers) is present and implemented correctly Testing with input file provided - no errors (successful run) Descriptive Comments throughout all program(s) and program header as requested Program name and submission format as requested (all in one file) Total % 10 5 5 100
