1. Create a subclass of the class you created in Assignment 2. (10 point)

2. Create at least 1 instance field (attribute) for your subclass (10 point)

3. Create getter (accessor) and setter (mutator) methods for the new instance field (10 point)

4. Create a Method to display your data (15 point)

Create a method called display, that simply prints out the values of all instance variables of your object

It must display all the fields from the super class, along with the new field that belongs to the subclass

This method will have no parameters and not return a value

5. Create 2 Constructors

Create a default constructor (no parameters) that assigns all your instance variables to default values. It should also set the fields for the super class as well. (10 point)

Create a parameterized constructor that takes all instance variables (from both superclass and subclass) as parameters, and sets the instance variables to the values provided by the parameters (15 point)

6. Testing your program. In the main method of Demo.java:

Create an instance of your new subclass (an object) by using the default constructor.

Call all your objects setter (mutator) methods to assign values to your object (5 point)

Call the objects display method, to print out it's values (5 point)

Create another instance of your class (another object) by using the parameterized constructor (10 point)

Call the objects display method, to print out it's values

7. Write Javadoc style comments for ALL of your methods. Including the methods in your super class. (10 point)

/* * This method will set the brand of instance variable * * @params String * * @return void */ public void setBrand(String brand) { this.brand = brand; }

/* * This method will return the price of instance variable * * @params void * * @return double */ public double getPrice() { return price; }

/* * This method will set the price of instance variable * * @params double * * @return void */ public void setPrice(double price) { this.price = price; }

/* * This method will display the values of instance variables * * @params void * * @return void */ void display() { System.out.println("Size :" + size); System.out.println("Brand :" + brand); System.out.println("Price :$" + price); }
