Question 3 (50 points) You have been hired by a local grocery store in order to update and expand the CashRegister Class that was discussed in class. Your task is to update class by adding functionality to it such that it will compute the total sales by all customer in a whole day, reset all variables after the store closes every d show the customer count per day, every day. In order to accomplish your task you need to do two smaller tasks: 1. Update the existing methods presented during lecture time, as needed, to accomplish the task described, above. 2. In order to help you further, you need to write 4 new methods, as follows: • addCustomerCount () - increments the customer count at the end of every customer sale end • getCustomerCount () - gets/returns the customer count; to be invoked at the end of every day • getSalesTotal() -gets/returns the total customer sales for all customers; to be invoked at the end of every day • resetSales () - clear daily instance variables that need to be cleared at the end of every day Important remarks: 3. You MUST USE the exact same methods names above, and to keep all the methods and their names that were discussed in lecture 4. Notice that the new methods do not take any input parameters 5. You may call your new instance variables using any names that you choose 6. Your updated CashRegister class will be tested by data of our choosing using the same method names mentioned in class and the new ones ab and therefore, it is important that you use the same method names and that they do the tasks described, above. Test the above class by: • Creating one CashRegister object; add two days sales. • For First day add sales for two customers. • Customer 1: items = 3 and Total = 5.40 • Customer 2: items = 4 and Total = 10.00 • For Second day add sales for 3 customers. • Customer 1: items = 2 and Total = 22.45 • Customer 2: items 5 and Total = 106.50 • Customer 3: items = 1 and Total = 20.00 A Sample output resulting from running the above test code is shown below: Day 1 sales Customer 1 Items - 3 Total - 5.4e Customer 2 Items - 4 Total - 10.ee Day Sales -15.40 Total Customers- 2 Edit Day 2 sales Customer 1 Items - 2 Total - 22.45 Customer 2 Items - 5 Total - 106.5e Customer 3 Items - 1 Total - 20.ee Day Sales -148.95 Total Customers- 3
