Simple Dog Inheritance

Geoffrey Challen // 2021.3.0

Create a public class named Dog. Dog should inherit from the Canine class shown below:

(You do not need to define Canine.)

You should provide a public constructor that allows the age of the Dog to be set (as a double) when it is created. assert that the passed age is not negative. You should not expose the age and do not need to provide either a setter or a getter for it. You should pass the kind "dog" to the Canine constructor when creating a Dog.

Dog should override toString and return a String in the following format: "This dog is (age) years old".
