Unit 5-WS03 Method Overriding and Polymorphism Name: The goal of this assignment is to begin to build your set of dasses that represents the following inheritance hierarchy: Vehicle Car Bike Problem #1 - Create 4 new classes, one called Vehicle, one called Car, one called Bike, and one called vehicle Main Problem #2 - Build the superclass Vehicle. It should have one instance variable speed that tracks the vehicle's speed and is set to zero when when a Vehicle object is created (referring to the constructor method). Problem #3 - Add three more methods to the vehide class using the following as a guideline: on ) - displays that the vehicle is running, off ) - displays that the vehicle is now off. getSpeed) ... returns the current vehicle speed. Problem #4 - Edit the Car class so that it inherits the Vehicle class and adds three more instance variables year (to track the year the car was made), make (who makes the car), and model (type of car). Problem #5 - The Car class should have a constructor method that retrieves the superclass instance variable(s) and requires three parameters fyear, make, and model) when constructing a car. Problem #16 - Add three more methods to the Car class using the following as a guideline: speedUp() .adds 8 to the speed of the car. slowDown() ... subtracts 11 from the speed ...do not allow negative speed. getVehicle)...prints vehicle year, make, model Problem #17 - Make the Bike class a subclass and give a a new instance variable type. The Bike constructor method should call the superclass instance variables) and should require a parameter to determine the type of the Bike object upon creation Problem #8 - Add 5 more methods to the Bike class: speedUp() .adds 3 to the speed of the bike. slow Down() subtracts 5 from the speed. getVehicle) - displays the type of bike. on() overrides superclass, displays bike ready off) - overrides superclass, displays not ready Problem #9 - Edit your classes so the vehicleMain code below yields the exact output shown after the code: public class vehicle Main public static void main(String[] args) { Vehicle this thing new Vehicle This thing on System.out.println("Speed is this thing.getSpeed mething off System.out.println(""); Cor cort-new Can 2014, "Toyoto","Carollo") carton System.out printSpeed is scarl getSpeed). forint) cort.speed Up System.out.println("Speed is corigetSpeedo cort slow Down.dk System.out.printinfort.getSpeed: cari.getVehicle cartoffe System.out.println(""); Skrbiket new Bile("Mountain bilond System.out.println("Spred is "bikelgetSpeed: bike speedUpl). bike speed Up bike slowdown System.out.println("Speed is "bike1.getSpeed: System.out.printin"type of bike bike.typek biel off Rideut The vehicle is now running Speeds: 0 The vehicle is now off.
