Well, now I know the answer to the first part, but now I need the answer to the second part, and the answer to the second part is related to the first part.

Part-II

(Only 30% of your total course grade)

In this part of the course work, you are required to design and implement a class called HP_Laptop with instance variables specific to this type of items, a constructor with parameters which initialises class data members and invokes the Item_in_Stock constructor when it is invoked using inheritance concept in java and initialises data members of Item_in_stock class as well. This class should be designed and implemented in a way that it overrides getItemCategory() that returns the category of the item, getItemName() that returns HP_Laptop and getItemDescription() that returns HP_I5_11G_8GB_1TB . The Class should also override the get_item_details() method to display the complete details of an item.

Task 2.1. Re-draw UML class diagram which was drawn in part 1 of the course work with this new class HP_Laptop. Relationships should also be represented.

Task 2.2. Implement a class called Item_check with a main method to test HP_Laptop class by defining object of the class and invoking methods.

Testing is an integral part of development. Write suitable test cases in the given format below for your classes.
