Question
Advanced Java Programming with Object-Oriented Programming Design
VERY IMPORTANT NOTE!!: This program for the question below MUST USE at least 2 CLASSES, getters/setters, etc and other object-oriented design (OOD) concepts because I'm in a more advanced Java class that requires me to utilize the concepts mentioned above. Also, I need detailed, but brief comments to most, if not all of the code to explain what is being used in the code and what is does so I have a better understanding of the code. I've seen answers to the question below already posted, however they don't utilize object-oriented design (OOD) concepts such as a minumum of two classes, getters/setters, etc which is required for this advanced Java programming class. So please......help and meet the requirements for this. Here's to hoping this works out......thank you!
A parking garage charges a $2.00 minimum fee to park for up to three hours. The garage charges an additional $0.50 per hour for each hour or part thereof in excess of three hours. The maximum charge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hours at a time. Write an application that calculates and displays the parking charges for each customer who parked in the garage yesterday. You should enter the hours parked for each customer via screen as user input. The program should display the charge for the current customer and should calculate and display the running total of yesterday’s receipts.
