ASSESSMENT DESCRIPTION:
Objectives
After completing this assessment, you should have developed skills to demonstrate that you are
able to:
Write classes that are subclasses of other classes
Write code that ove
ides behaviour of inherited methods.
Write code that exploits the benefits of polymorphism
Observe/apply principles of good object-oriented design
1. Individual understanding of Object Oriented Programming principles
Write about 500 words to explain what you have learnt in week 9 and week 10. Use appropriate examples
to illustrate your understanding.
2. Program
2.1 Background
The classes you write will be to represent a variety of product types available at a supermarket.
They will all have a common method to produce a line of output suitable to be included in a
docket. However, depending on what type of product it is, this output will contain different sort
of information.
For all products, the output line should include:
The name of the item
he ID of product
The price of the item
The amount of the price which is a tax-component (explained below)
Depending on the type of product, the following additional information should be output:
If it is a Fresh Fruit item, the weight of the item (e.g. the Apple is 100 grams,
the watermelon is 1200 grams).
If it is a Packaged item, the quantity of units in the package (e.g. 4 eggs in the package,
20 chocolate bars in the bag), and a use-by date.
The tax-component is calculated from the price of the item, and the following rates are used:
For Fresh Fruit items, 0%
For Packaged items, 10% of the price

2.2 Tasks
1. Create a class named Product to be the superclass of all products. It should have
suitable constructors to aid with polymorphic behaviour, and contain suitable attributes
to store the information that is common to all product types (but whose values vary for
each instance of that product type), and appropriate accessors. For all products, the
toString method should return only the name and ID of the product.
2. Create a class to represent Fresh Fruit items. It should be a subclass of the class made in
task 1. Ensure that it contains appropriate attributes to store additional information
specific to fresh fruit. Ensure that there is a suitable constructor to set all values
appropriately, and that there are appropriate accessors to obtain all information
elevant to fresh fruit. Ove
ide toString() method so that it return all relevant
information to the fresh fruit.
3. Create a class to represent Packaged items. It should be a subclass of the class made in
task 1. Ensure that it contains appropriate attributes to store additional information
specific to packaged items. Ensure that there is a suitable constructor to set all values
appropriately, and that there are appropriate accessors to obtain all information
elevant to packaged items. Ove
ide toString() method so that it return all relevant
information to the Packaged items.
4. Create a driver class which will have main method and following functionalities.
Create ten different products and display them on console.
Ask user to select the products that they want to buy by selecting the IDs.
User can buy multiple products in one purchase.
Use proper get methods to find total amount and total tax component.
Display the docket which will have information about total amount due
and total tax value in purchase.
5. Create a class diagram for above mentioned classes. Show all attributes, methods and
proper relationships between classes.
