CA3 Group Assignment
January 2023 Semester
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:
