You will need to parse this data and load it to the inventory of the dealership. After loading the inventory with the data, you will verify that the inventory has been loaded correctly by using the following methods in the Inventory class.

Vehicle findCheapestVehicle()

Vehicle findMostExpensiveVehicle()

double getAveragePriceOfAllVehicles()

Chevrolet	Corvette	1963	200000	FALSE
Chevrolet	Corvette	1957	130000	TRUE
Bugatti	Chiron	2022	3500000	FALSE
Genesis	G90	2022	495666	FALSE
Shelby	Cobra 427	1965	2000000	TRUE
Chevrolet	Camaro	1969	150000	TRUE
Ford	Mustang Bullit	1968	180000	FALSE
Ferrari	Testarossa	1992	180000	FALSE
Porche	911	2022	200000	TRUE
Bentley	Bacalar	2022	1900000	TRUE

The most expensive vehicle is the Bugatti Chiron, cheapest vehicle is the Chevy Corvette 1957 and the average price for all vehicles is $893,566.60.

Write JUnit tests to verify this result in the DealershipTest.java class.

When finished, submit Dealership.java and DealershipTest.java.
