Every summer, Leeland Lakeside resort rents cabins by the week. Create a class named CabinRental that includes an integer field for the cabin number and a double field for the weekly rental rate. Include get methods for these fields and a constructor that requires an integer argument representing the cabin number. The constructor sets the weekly rate based on the cabin number; cabins numbered 1, 2, and 3 are $950 per week, and others are $1,100 per week. Create an extended class named HolidayCabinRental that is used for rentals during weeks that include summer holiday weekends. The constructor for this class requires a room number and adds a $150 surcharge to the regular rental rate. Write an application named DemoCabinRental that creates an object of each class, and demonstrate that all the methods work correctly.
