1. Create a subclass Create a sub class that inherits everything from your base class. (For example, if Car is the base class then SportsCar could be your sub class) [1 point] Provide at least one additional attribute to your subclass [1 point] Create a default constructor for the subclass, that uses super to call the base class default constructor. [1 point] Create a parameterized constructor for the subclass, that uses keyword super to pass the inherited parameters to the base class. [1 point Override the display0 method to print out all the instance variable values from the base class, and also from the sub class. [1 point] o Create gettter/setter methods for it. lt should set all attributes in the subclass as well as the super class to default values It should set all attributes in the subclass as well as the super class to the values that are passed in to the constructor It should also have a method called toString and printToFile (see instructions in part 2 below) 2. Create an Interface Create an interface called Printable that has the following methods declared: display0, printToFile0 and toString0 Make your subclass above implement the interface. This includes writing the bodies of all 3 methods. You should already have a display method, so you need to implement the other 2 methods [1 point] Override the toString method in the subclass in part 1 [1 point] .Implement the print ToFile method in the subclass in part 1. The method should be able to append to a file, not overwrite it. [1 point 3. Update main method In your main method, create 2 new object using your subclass . Create one object using the no-arg (default) constructor of your sub-class. [1 point] Create one object using the parameterized constructor of your sub-class. [1 point] Loop (iterate) through each object calling the print ToFile method. [1 point] o Call the set methods to set all attribute data associated to that object. o Create an ArrayList of all your objects, including the original ones created using the Super class and the new ones created using the Base class. [1 point] o
