Apply the Java concepts that you learned (OOP, polymorphism, interfaces, packaging, …) as well as SOLID design principles to design/extend a Parking Garage application and implement it using the Java/C++ programming language. This application manages a parking space for a configurable maximum number of vehicles. The designed application must handle the following functions: ● Each garage slot has a width and depth that describes the slot dimensions. ● The garage consists of a configurable maximum number of slots with different dimensions. ● Each vehicle shall be identified by a model name, unique identification number, Model year and vehicle dimensions (width and length). ● Park-in function that marks the arrival time of a vehicle if there is an available slot that matches vehicle dimensions. ● The slot selection for vehicle park-in could be done using multiple algorithms: ○ First Fit selection where the first slot with big enough dimension to host the vehicle will be selected ○ Best Fit selection where the slot with the best dimension match should be used where the wasting area of the slot is minimized. ● Slot selection algorithms could be extended in the future version of the application. ● Park-out function that marks the departure time of a vehicle ● Calculate the parking fees during the park-out based on the time-of-stay with an hourly rate that depends on the slot dimensions i.e slot with width = 120cm and depth = 200cm could cost 10 EGP per hour. These costs should be configured during the slots configuration during application startup ● Calculate the total income as well as the total number of vehicles that used the parking garage at any given point in time. ● Display the available parking slots for specific vehicle dimensions. ● Enrich your application with the capability to handle a set of exceptions that can happen during user interaction and through any other calculations. The displayed error message for exceptional behavior should be descriptive.

SOLID design principles to design/extend a Parking Garage application and implement it using the
Java/C++ programming language. This application manages a parking space for a configurable
maximum number of vehicles. The designed application must handle the following functions:
● Each garage slot has a width and depth that describes the slot dimensions.
● The garage consists of a configurable maximum number of slots with different dimensions.
● Each vehicle shall be identified by a model name, unique identification number, Model year and
vehicle dimensions (width and length).
● Park-in function that marks the arrival time of a vehicle if there is an available slot that matches
vehicle dimensions.
● The slot selection for vehicle park-in could be done using multiple
○ First Fit selection where the first slot with big enough dimension to host the vehicle will
be selected
○ Best Fit selection where the slot with the best dimension match should be used where
the wasting area of the slot is minimized.
● Slot selection algorithms could be extended in the future version of the application.
● Park-out function that marks the departure time of a vehicle
● Calculate the parking fees during the park-out based on the time-of-stay with an hourly rate that
depends on the slot dimensions i.e slot with width = 120cm and depth = 200cm could cost 10
EGP per hour. These costs should be configured during the slots configuration during application
startup
● Calculate the total income as well as the total number of vehicles that used the parking garage
at any given point in time.
● Display the available parking slots for specific vehicle dimensions.
● Enrich your application with the capability to handle a set of exceptions that can happen during
user interaction and through any other calculations. The displayed error message for exceptional
behavior should be descriptive.
