Project 1 – Parking Spot System - Requirements
A small system is required that will help manage cars at a parking site for a company. You are
to develop a system that has exactly following four classes:
•
•
•
•

Application class
CarPark class
ParkingSlot class
Car class

Application is the Console (Text Based) Interface class including the main() method and
handling all inputs and outputs.
CarPark is responsible for maintaining a list of available parking slots. You should be able to
find a slot, add a slot, delete a slot, and provide a list of all slots included in the car park.
There are two types of parking slots: slots only for visitors and slots only for staff members. A
parking slot must have an identifier, which starts with a capital letter, followed by a two-digit
number e.g. “D01”, “E27”. A parking slot also should know if a car and what car is parked in
the slot. You must be able to add a car to the slot and remove a car from the slot.
A car will be identified by its registration number. A registration number always starts with a
capital letter, followed by a four-digit number e.g. “T2345”. A car should have an owner and
knows if the owner is a staff member.
For this assessment, you do NOT need to maintain a list of parked cars in any of your classes.
The office manager requires a simple Console (Text Based) Interface that will have the
following menu items.
1. Add a parking slot, all information provided by users
2. Delete a parking slot by slot ID (only if not occupied)
3. List all slots in a well-defined format with information including slot ID, slot type,
whether occupied, and if occupied, show the car registration and the owner.
4. Park a car into a slot (provide slot ID and car information)
5. Find a car by registration number and show the slot and the owner if the car is in
6. Remove a car by registration number
7. Exit

Required conditions to be checked for user inputs:
1. User inputs for menu options, car information, and parking slot information should not
crash the program
2. Parking slot number must be an uppercase letter followed by 2 digits
3. Car registration number must be an uppercase letter followed by 4 digits
4. Each slot should have a unique slot number
5. A parking slot cannot be deleted if there is a car being parked there
6. Visitor car can only be parked in a visitor slot and staff car can only be parked in a
staff slot
7. A car can only be parked in an unoccupied slot
8. A car can only be parked in one slot
