Implement a car access parking system based on the requirements bellow.
Note 1 - Source folder contains some classes which can be used as starting point or refference for implementing the application.
Note 2 - There is no need to implement access control levels (user and admin) as represented in the use case diagram bellow.
Note 3 - For storing cars on disk check utility classes given as example in 'files' package.
Enter Car Park
- car is identified by plate number
- if there are free parking spaces car is allowed to enter if not the car access is denied
- access is denied if a car with the same plate umber is already parked
Check Space Available
- parking has a limited number of places available (configurable through the app)
- if number of spaces available is 0 car is denied access
Exit Car Park
- when leaving total stay cost is calculated
- after leaving an access log for that car and period is stored for reporting purpose
Calculare Usage Cost
- cost of parking is calculated in increments of 1 SECOND to make it more easy to tests the system
- 1 SECOND costs 1 RON
View Current Parked Cars
- display all cars currently parked. Display : plate number, entry time, current cost
- display available free spaces
View All Past Entries for a Car
- display all past entries for a car. Display: plate number, entry time, total stay (in seconds), total cost;
- display total cost for all stays
View All Unique Past Entries
- display all unique cars eneterd in parking lot in the past. Display: plat number and number of entries for each car
- Car access details will be stored in a persistant storage on disk as files and the state is not lost when the application is restarted.
- Car access details can be stored using one of the 2 Java mechanisms: JSON objects, Serialization.
- Minimal unit-tests should be provided to demonstrate the correct behaviour of the system.
