Question

Assignment:

You are to create seven classes that represent a Zoo. The classes are define as follows:

1. Zoo

2. Enclosure

3. Animal

4. Crocodile

5. Gazelle

6. Lion

7. Zebra

1. Zoo:

Required member variables:

private String name;

private String address;

private Enclosure[] enclosures;

private int area;

private double budget;

2. Enclosure:

Required member variables:

private String biome;

private Animal[] animals;

3. Animal

Required member variables:

private String name;

private String genus;

private String species;

private Zoo currentZoo;

protected Animal enemy;

protected String prefferedBiome;

For classes 4-7, there are no required member variables.

All the classes must have getters and setters for each of their member variables. All of the classes must

have overridden toString() and equals(...) functions. All classes must be in separate files. Crocodile,

Gazelle, Lion and Zebra are Animals. Class Animal must implement this interface:

interface

Feedable

{

void

getFeedingInstructions();

void

feed();

}

All the child classes of Animal must have its own overridden

getFeedingInstructions();

and

feed();

functions.

The classes need to be implemented in a way that makes this main function:

public static void main(String[] args) {

//Creating a new Zoo.

Zoo laZoo = new Zoo("Los Angeles Zoo", "5333 Zoo Dr, Los Angeles, CA 90027", 133, 0);

//Creating two different Enclosures.

Enclosure firstEnclosure = new Enclosure("Savanna");

Enclosure secondEnclosure = new Enclosure("River");

//Creating our animals.

Zebra zeb = new Zebra("Zebby");

Gazelle gaz = new Gazelle("Gaz");

Crocodile croc = new Crocodile("Gena");

Lion leo = new Lion("Leo");

//Trying to add croc to the firstEnclosure, but Crocodiles can't live in the Savannah, so it prints an error

message.

firstEnclosure.addAnimal(croc);

//Adding leo to the first enclosure.

firstEnclosure.addAnimal(leo);

//Adding croc to the second enclosure.

secondEnclosure.addAnimal(croc);

//Trying to add zeb to the secondEnclosure, but Crocodiles and Zebras are enemies, so it prints an error

message.

secondEnclosure.addAnimal(zeb);

//Creating a new enclosure just for the herbivores.

Enclosure thirdEnclosure = new Enclosure("Savanna");

//Adding zeb and gaz to the third enclosure.

thirdEnclosure.addAnimal(zeb);

thirdEnclosure.addAnimal(gaz);

//Adding all three enclosures to the zoo.

laZoo.addEnclosure(firstEnclosure);

laZoo.addEnclosure(secondEnclosure);

laZoo.addEnclosure(thirdEnclosure);

//Printing the Zoo:

System.out.println(laZoo);

//Getting the feeding instructions for all the animals:

laZoo.getFeedingInstructions();

//Feeding the animals:

laZoo.feed();

//However, an error message is printed because the Zoo doesn't have enough money to feed all the animals,

so we add more money to the Zoo.

laZoo.setBudget(999999999);

//Successfully feeding the animals!

laZoo.feed();

}

Output this:

Error! Gena cannot live in the Savanna. addAnimal failed.

Error! Zebby cannot live with Gena, as they are enemies. addAnimal failed.

Los Angeles Zoo

==========

Address: 5333 Zoo Dr, Los Angeles, CA 90027

Area: 133

=========

Enclosures:

1. Savanna:

a) Leo (Panthera leo)

2. River:

a) Gena (Crocodylus niloticus)

3. Savanna:

a) Zebby (Equus quagga)

b) Gaz (Rhim gazelle)

How to Feed:

1. Savanna:

a) Meat 4000$

2. River:

a) Meat 5000$

3. Savanna:

a) Grass 600$

b) Grass 900$

Feeding failed! Out of funds.

Feeding completed successfully.
