Correct Answer to whether there is any inconsistent class:
Yes, there is an inconsistency. As both MeatTopping and VegetableTopping have the same
subclass which leads to the inconsistency.
Explanation of inconsistency:
As both MeatTopping and VegetableTopping have the subclass MeatyVegetableTopping. As
a result, MeatTopping and VegetableTopping are disjointed, resulting in inconsistency.
Describe a way to resolve the inconsistency:
We've been told to make all of the classes disjoint. As a result, the classes MeatTopping and
VegetableTopping, which share the same subclass, are incompatible. We need to remove the
disjointness between the two classes to fix this inconsistency.
Add two more pizza and explanation:
I’ve added two more pizzas namely ChillyChickenPizza and ChetnaduChickenPizza under
the subclass NamedPizza which is a subclass of Pizza which is a subclass of
pizzaDomainConcept.
Add two more PizzaBase and explanation:
I’ve added the two PizzaBases namely Thick and Thin under the subclass PizzaBase which is
a subclass of pizzaDomainConcept.
Add two more PizzaTopping and Explanation:
I’ve added two more PizzaToppings namely ChillyChickenTopping and
ChetnaduChickenTopping under the subclass MeatTopping which is a subclass of
PizzaTopping which is a subclass of pizzaDomainConcept.
Add atleast four more properties:
I’ve added four more properties namely hasCountry, hasSize, hasTemp, and hasSauce. The
four additional properties are part of the topObjectProperty's attributes. To determine the sort
of pizza required, these four characteristics can be added to pizza classes.
