...since each animal makes a different sound anyway so what's the point of not making everything abstract?

12,754 PointsI can think of two possible reasons why a developer might not want an abstract class
makeSound()
for the animal class.Your code never requires the animals to make sound, making the
makeSound()
method unnessesary.Like how the auto class was separated into motorcycles and cars subclasses, you might also want to separate the animal class into soundAnimals and quietAnimals (for animals that don't make sounds such as Sea Urchins). In that case, you would probably only want soundAnimals to have the
makeSound()
method.In many cases creating a
makeSound()
abstract class for the animal class would be a great idea. I know you were just thinking aloud, but I thought you might want to hear what some possible exceptions might be. Hope it helps
