A Car class which is a subclass of FuelVehicle that has:
one additional private instance variable nbSeats
one constructor to initialize the instance variables
overrides getCost method by adding nbseats*baseFee to mileageFees
асcessors
A Truck class which is a subclass of FuelVehicle that has:
one private instance variable capacity
one constructor to initialize the instance variables
overrides getCost method by adding baseFee*capacity to mileageFees
асcessors
A Bicycle class that extends RentedVehicle that has:
- one additional private instance variable nbDays indicating the number of days it is rented.
- one constructor to initialize the instance variables
- overrides getCost method to return baseFee * nbDays
- accessors
Implement all five classes with their accessor and mutator methods.
Write an application class that generates 6 objects randomly from either a Car, or a Truck, or a
Bicycle class. You need to generate an integer random number between 1 and 3 and based on its
value you generate your object from one of the three classes. Your generated objects will be
stored in a RentedVehicle array.
Write a static method in your test class that takes an array of RentedVehicles and prints the
following for each element of the array:
- if the object is a car print its name and the number of seats and cost.
- if it is a Truck, print its name and capacity and cost.
- if it is a Bicycle, print its name and how many days it is rented and cost.
Test your class with appropriate data.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F387bd6c6-7c1f-4d62-ab7b-2149e67d2686%2F78f8c977-a4cd-42da-a47c-63f4bcdbe80a%2F6u5wv9_processed.png&w=3840&q=75)

Write Java code for the following problem.
Consider the following inheritance hierarchy.
RentedVehicle
FuelVehicle
Bicycle
Car
Truck
A class RentedVehicle that has:
One private instance variable baseFee of type double
One constructor to initialize the instance variable
One instance method getCost () that returns the base fee
Accessor methods for the instance variables
A subclass FuelVehicle that has:
one additional private instance variable nbKms indicating the total number of kilometers
traveled.
one constructor to initialize the instance variables.
one instance method getMileageFees to return the fees due to mileage based on the following:
If nbKms < 100 mileagefees=0.2*nbkms
If 100<=nbKms<= 400 mileagefees=0.3*nbkms
If nbKms>400 mileagefees=0.3 times 400 plus 0.5 times the extra kilometers above 400.
