ent, you'll need to build and run a small Zoo in Lennoxville. All classes must be created in
Animal (5)
First, start by building a class that describes an Animal at a Zoo. It should have one private instance
variable for the name of the animal, and one for its hunger status (fed or hungry).
Add methods for setting and getting the hunger satus variable, along with a getter for the name. Consider
how these should be named for code clarity. For instance, using a method called hungry () to make the
animal hungry could be used as a setter for the hunger field. The same logic could be applied to when it's
being fed:
public void feed () {
this.fed = true;
Furthermore, the getter for the fed variable could be named is Fed as it is more descriptive about what it
answers when compared to get Fed. Keep this technique in mind for future class designs.
Zoo (10)
Now we have the animals designed and ready for building a little Zoo!
