added to your scenario. 5. In your journal, create an entry entitled “Class Diagram”. Create a diagram that shows the relationship between an instance,subclass, and superclass using a real-world animal or plant example. 6. In your journal, create an entry entitled “Classes”. In this entry, explain to someone who doesn't understand classes and...
