Submission Date: 12 February 2024, 11.59 a.m.

Continuous Assessment 3 Group Assignment (40%)

The Java application constitutes 30% of your overall grade, while the class

presentation is another 10%. Total marks for this assessment is 100 marks.

Project Task:

To enhance the experience of zoo enthusiasts, you are required to develop a

command line application using any Java IDE. This application should simulate the

management of a virtual zoo, including handling animals, enclosures, and

zookeepers. The Java application constitutes 30% of your overall grade, while the

class presentation is another 10%. The total marks for this assessment are 100

marks.

Project Requirement

With what you have learned from the module, you are task to develop the Java

application with the following:

1. You are required to write FOUR (4) Java classes.

a. Zoo

b. Animal

c. Enclosure

d. ZooManagement (Main Class)

More information about these Java classes will be on the next section of this

document.

2. Implement Error Handling methods on relevant functions.

Your program should handle errors effectively, ensuring the program only

terminates when the user chooses to exit, rather than due to unhandled

exceptions or runtime errors.

Class Descriptions

For each of the FOUR (4) Java classes listed above, you are to refer to their UML

class diagrams below, as well as their field and method descriptors, to determine a

way to code them. For each class, you are also to:

Define appropriate constructor(s) for them.

Define all needed getter and setter functions for them.

Note: All fields and methods listed in the UML class diagrams are COMPULSORY.

You can add any number of fields and methods that you need to help you implement

the class.

Zoo

- name : String

- description : String

- enclosures : ArrayList<Enclosure>

+ <<constructor>> Zoo(name : String, description : String,

enclosures : ArrayList<Enclosure>)

+ getTotalEnclosureArea() : int

+ countEnclosures() : int

Field Descriptors

name: Name of the Zoo.

description: Description of the Zoo.

enclosures: A list of all the enclosures in the Zoo.

Method Descriptors

getTotalEnclosureArea(): Counts the total area across all enclosures inside

the enclosures ArrayList.

countEnclosures(): Counts the total number of Enclosures in the enclosures

ArrayList.

Enclosure

- name : String

- area : int

- animals : ArrayList<Animal>

+ <<constructor>> Enclosure(name : String, area : int, animals :

ArrayList<Animal> )

+ countAnimals() : int

+ getUtilisedArea() : int

+ getUtilisedAreaPercentage() : double

+ countSpecies() : int

+ addAnimal( animal : Animal ) : bool

Field Descriptors

name: Name of the enclosure.

area: Number of units of space in the enclosure. Determines how many

animals can be stored in the enclosure. See areaNeeded in Animal for more

information.

animals: List of animals in this enclosure.

Method Descriptors

countAnimals(): Counts the total number of animals inside the animals

ArrayList.

getUtilisedArea(): Gets the total units of space that the animals in the

enclosure are taking up.

getUtilisedAreaPercentage(): Returns a value between 0 to 1. For example, if

75% of the available area is used by animals, this will return 0.75.

countSpecies(): Counts the number of unique species in this enclosure.

Returns the number of unique species in this enclosure.

addAnimal(): Adds an animal to the animals ArrayList if there is enough

space. Returns true if successful. Otherwise returns false.

Animal

- species : String

- enclosure : Enclosure

- areaNeeded : int

+ <<constructor>> Animal(species : String, enclosure : Enclosure,

areaNeeded : int)

+ hasCompanion() : bool

Field Descriptors

species: The species of this Animal.

enclosure: The Enclosure that this Animal belongs to.

areaNeeded: The amount of area this Animal takes up. See area in Enclosure

for more information.

Method Descriptors

hasCompanion(): Does the animal have another companion of the same

species inside of its enclosure? Returns true if so, otherwise returns false.

ZooManagement

- zoos : ArrayList<Zoo>

+ main(args : String[])

+ manageZoos()

+ manageEnclosures()

+ manageAnimals()

In ZooManagement, you will be required to code the following functionalities:

1. Manage Zoos: This option will open a set of suboptions that allow the user

to...

a. Create new Zoos.

b. Delete existing Zoos.

c. Calculate and output the total area of all enclosures in the zoo.

d. Count and output the total number of enclosures.

2. Manage Enclosures: This option will open a set of suboptions that allow the

user to...

a. Add an Enclosure to a Zoo.

b. Delete an existing Enclosure from a Zoo.

c. Get the utilised area in a given enclosure.

d. Get the percentage of utilised area in a given enclosure.

e. Count the number of species in an enclosure.

3. Manage Animals: This option will open a set of suboptions that allow the user

to...

a. Add animals to an enclosure.

b. Remove animals from an enclosure.

c. Check if an animal has a companion in its enclosure.

Note: The user will be able to continuously select commands from ZooManagement

until they choose to exit the program.

Documentation

On top of the Java Application development, you will also be required to submit a

report with the following documentation:

A short reflection on this assignment with the following pointers:

1. Things you have learnt through doing the assignments

2. Screenshot and explanation on unresolved/unachievable requirements.

Submission Instructions

You are required to put the following files into a ZIP folder for submission:

1. All Java class files required to run the program (other project files are NOT

required).

2. Your assignment report
