First develop a Creature class. Creatures have names. If I have a Creature

object I can ask it to speak$().$ It will say: $$My name is $...$ and I am Creature.$$

There should also exist more specific types of Creatures, e$.$g$.$ Dogs. So$,$ a

Dog is a Creature. A Dog will say: $$My name is $...$ and I am a Dog: woof.$$

Do the same with Cows
