Say you want to store the information about a number of
pets in an array. Typical
information that you could store for each pet (where
relevant) would be
• Breed of animal
• Animal's name
• Its birth date
• Its sex
• Whether it has been sterilised or not
• When it is due for its next inoculation
• When it last had its wings clipped
For each type of pet (eg. dog, cat or bird) you would
typically define a class to hold
the relevant data.
Note: You do not need to implement these classes. Just
answer the following
questions.
3.1.1 What would be the advantage of creating a superclass
(eg. Pet) and
declaring an array of Pet objects over simply using an
array of Objects,
storing each of the instances of the different pet classes
(eg. Dog, Cat or
Bird) in it?
3.1.2 Would you define Pet as a class or as an interface?
Why?
