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 for each customer from the data in the text file.

A suitable inheritance hierarchy that 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: o Instance variables o Constructors o Accessor and mutator methods o Suitable toString( ) methods o Any other appropriate methods ? Write a class LabExam which utilizes the following: o An Array of Customer objects o A method that reads the input file provided and stores the objects in the array of Customers. o A method that sorts the array of Customers in ascending order by the customer ID. (you may use Arrays.sort(custList)) o A method that formats and prints the output report. 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 45 Customers per page. ? All money amounts and percentages should be displayed with 2 decimal places and commas after each thousand. o 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. o Any other helper methods used to meet the requirements of the assignment. o The main method will call all the other methods that will: ? Read the text file and store the objects in the array ? Sort the objects ? Format and print the report
