Insturctions:
This assignment will assess your understanding of void and value returning static methods.
Your cousin owns an automotive maintenance shop that performs routine maintenance on cars. He has asked you to write a program that will provide a list of services (and their respective prices) to users and allow them to choose any, or all, services they would like and display the final price, including a 28% labor charge, a 9% markup if the car is an import, and an 8% sales tax.
Task
To accomplish the above, do the following:
Write the two methods outlined below.
Test your program and screenshot your successful test.
carMaintenance method
This method should accept the make of the car as a parameter (e.g., BMW, Ford, Ferrari, etc.). It should display the services and their prices as…
