Java (derived classes) - Pet Information
![The base class Pet has protected fields petName, and petAge. The derived class Dog extends the Pet class and includes a private field for
dog Breed. Complete main() to:
• create a generic pet and print information using printinfo().
• create a Dog pet, use printinfo() to print information, and add a statement to print the dog's breed using the getBreed() method.
Ex. If the input is:
Dobby
2
Kreacher
3
German Schnauzer
the output is:
Pet Information:
Name: Dobby
Age: 2
Pet Information:
