Question part 3: Draw a UML class diagram with all the classes and relationships. More info: In this last and final part of the course work you are required to change the definition of the Item_in_Stock class to make it an abstract class and change the getItemCat(), getItemName() and getItemDescription() definitions to make them abstract methods. You are then required to design and implement three classes which are derived from Item_in_Stock class to fully demonstrate the concept of inheritance and polymorphism. Implementation of HP_Laptop class in part II should have given you an idea of inheritance and polymorphism. Three sub classes, one class against each category (Computers, Laptops and Accessories), should contain appropriate constructors, instance variables, setter and getters methods and overridden methods for getItemName(), getItemDescription() and get_Item_details() method. You should be creative and come up with your own ideas of sub-classes. (please see the photo if…

These operations are public and the Vehicle contract is stable – it will not change. (ii) We think we’ll be able to take advantage of code-reuse, so your team must introduce an…
