Assessment Details
Consider a company XXX sells electronic products. There are three types of products they sell,
namely (i) Smart Phone, (ii) Television and (iii) Laptop. The following table lists the product
descriptions that are stored for each individual product type.

Task 1: Create an appropriate hierarchy of classes using Inheritance. Place the product
description fields in super class or subclass, where it is appropriate. Define constructors and
proper get and set methods for all the fields.
The company XXX maintains a stock of their products. It imposes restrictions on the quantity of
each individual product they stock as well as an overall restriction on the total number of products
they can store. While stocking the products in the storage, they maintain a digital repository. The
repository can be populated using a file or can be manually entered from the console. Consider the
file “Stocks.txt” as the template for populating the repository.

Page 1 of 3Task 2: Define a class “Stocks” whose object can be used as the repository. Moreover define
an Interface “StockLimit” that will define the maximum number of each products and the
maximum number of total stock that XXX can store in its repository.
Task 3: Define a method to read the text file “Stocks.txt” and generate objects of the
corresponding type of product using the corresponding classes’ constructor. You are to create
as many objects as indicated by “Quantity” in “Stocks.txt”.
Task 4: Maintain the current level of stocks for each element and check it with the maximum
limit (as defined in Task 2) before creating the product objects in Task 3. Moreover, define
an exception class “StockLimitException” and throw it when the total stock limit is reached
to abort further attempt to create product objects. Also include appropriate try-catch block.
Task 5: Similarly, define a method to populate the product objects from Console using the
same format as described in “Stocks.txt”
Task 6: Save the current repository in a file (ex., “Repository.txt”). Create one record for
each product in your digital repository and write the quantity field as 1.
Task 7: Define an appropriate test class with main function to demonstrate the
functionalities of your code.
