A zoo is developing a new caretaking system. You are tasked with implementing the code tracking a habitat's state. You are already given a basic implementation of the class Habitat.

The class Habitat has the following instance member fields:

An int field maxPopulation;

A char field animalSize;

A char field animalDiet;

As most of the Zoo's animals have similar needs, the class is instantiated through a no$-$args constructor that sets some default values.

The following static constants have already been defined:

An int constant SMALL$\_$POPULATION that stores the number $6$;

An int constant MEDIUM$\_$POPULATION that stores the number $12$;

An int constant BIG$\_$POPULATION that stores the number $18$;

A char constant SMALL$\_$ANIMAL that stores the character S;

A char constant MEDIUM$\_$ANIMAL that stores the character M;

A char constant BIG$\_$ANIMAL that stores the character B;

A char constant HERBIVORE that stores the character h;

A char constant OMNIVORE that stores the character o;

A char constant CARNIVORE that stores the character c;

Now, define three more public constants, DEFAULT$\_$POPULATION$\_$SIZE, DEFAULT$\_$ANIMAL$\_$SIZE, and DEFAULT$\_$ANIMAL$\_$DIET, respectively initialized to MEDIUM$\_$POPULATION, SMALL$\_$ANIMAL, and HERBIVORE.
