Question

Java Code:

Problem #1:

Create an inheritance hierarchy of Rodent: mouse, gerbil, hamster, guinea pig.

In the base class, provide methods that are common to all rodents based on behaviours you find with a quick Internet search. Be sure to document the behaviours you implement (e.g., eat, sleep, groom, move, etc.). Each behaviour should print its action to standard output (e.g., rodent eating).

Next, refine these behaviours in the child classes to perform different behaviours, depending on the specific type of rodent, but only if the behaviour is actually different (e.g., mouse eating seeds or guinea pig eating grass). If you are having difficulty coming up with various behaviours, create a discussion on the Landing to compare notes with others taking the course.

Test your Rodent classes by writing a main() class and creating instances of every rodent, and demonstrate all the behaviours for each rodent.

Answer 1

I have implemented the inheritance hierarchy of Rodent Using Java. Please find the following Code screenshot, output, and code.
