3. (5 pts Inheritance) Hand-write two Java classes, Car and Truck. They are both subclasses of Vehicle. a. A car has an additional instance variable, numberOfDoors. b. A truck has an additional instance variable, numberOfAxles c. Write a constructor that requires input for the instance variables of each class (including receiving registration number, owner name, price, and year manufactured, and calling super with them) d. Write getters and setters for all instance variables for both classes (e.g., Car and Truck)
