- Homework Assignment Chapter 10b Create a new Java Project named Chap10b Create a class named Vehicle that acts as a superclass for vehicle types. The Vehicle class contains private data fields for the number of wheels and the average number of miles per gallon. The Vehicle class contains getters and setters for the data fields. The Vehicle class also contains a constructor receiving integer parameters for the number of wheels and average miles per gallons, and a display() method that prints the required output (use get methods). Create two subclasses, Car and MotorCycle, that each extend the Vehicle class. Each subclass contains a constructor that accepts the miles-per-gallon value as an argument and forces the number of wheels to the appropriate value-2 for a MotorCycle and 4 for a Car. Use the superclass constructor to set the wheels and mpg data fields (use the super keyword). Write a UseVehicle class to instantiate one object of each subclass and calls the display method to print…Question - Create a class named Pizza with the following data fields: description - of type String price - of type double The description stores the type of pizza (such as sausage and onion).
