Lab Project for Methods
You are employed by the
Rainbow Paint Store.
For the purposes of this program, the Rainbow Paint Store
RED and GREEN gallons of paint.
Your task:
1. From main, ask the customer which paint color they wish to purchase and how many
full gallons of paint are needed. Design the program to allow the customer to make
additional purchases of either color of paint.
2. Establish a method to deal with each color of paint (2 methods).
The method for the red paint: determine the cost of the paint based upon $21.95 per
gallon. Return the total cost to main.
The method for the green paint: determine the cost of the paint based upon $19.95
per gallon. Return the total cost to main.
3. Establish a method to print the store title for billing purposes.
4. Establish a method that determines a total bill for the customer. This method will
receive the totals from the two paint methods, will compute the final total cost, and
will add 8% sales tax to the order. Return this final total to main.
5. Establish a method to print a thank-you message for buying at this store.
6. Print a bill for the customer. The bill is to be developed in the following order:
the store name, the total cost of each paint color, the total bill with sales tax, and the
thank you message.
7. Be sure that the money amounts are printed as money amounts.
