Data

The Model class will create 5 FootballPlayer objects which now have also number and position as attributes, besides their Person attributes4 using the data below

name=Marcus Allen, height=5'2", weight=200, hometown=Upper Marlboro, Md., highSchool=Dr. Henry A. Wise, Jr., number=2, position=S

name=Kyle Alston, height=5'9", weight=180, hometown=Robbinsville, N.J., highSchool=Robbinsville, number=37, position=CB

name=Troy Apke, height=6'1", weight=220, hometown=Mt. Lebanon, Pa., highSchool=Mount Lebanon, number=28, position=S

name=Matthew Baney, height=6'0", weight=225, hometown=State College, Pa., highSchool=State College, number=35, position=LB

1 using the no-parameter constructor

Functionality

This assignment is a follow up from the previous assignment with one update:

There is a new class FootballPlayer. FootballPlayer is a Person with some extra attributes.

Model will now store the FootballPlayer objects instead of Person objects.

The ArrayList should be then an ArrayList instead of the previous ArrayList.

You will keep the MVC functionality from the previous assignment

This new addition, of a specialized class FootballPlayer in Model, shows how the MVC architecture works. There will be changes in Model but Controller and View stay the same.

Controller will be simpler having only one line calling the new method in Model, getData(). This method returns an ArrayList with one line (one big String) for each Person in the ArrayList.

As in the previous assignment, the main objective is to make View display the information about the 5 objects (now footballPlayer instead of Person). These 5 objects are created in Model in the method loadData( ). Controller will retrieve the data from Model using the method getData() and pass it to View. View will use the method basicDisplay(ArrayList arr) to display data from each object with the following result:

Person{name=Marcus Allen, height=5'2", weight=200, hometown=Upper Marlboro, Md., highSchool=Dr. Henry A. Wise, Jr.} FootballPlayer{number=2, position=S} Person{name=Kyle Alston, height=5'9", weight=180, hometown=Robbinsville, N.J., highSchool=Robbinsville} FootballPlayer{number=37, position=CB} Person{name=Troy Apke, height=6'1", weight=220, hometown=Mt. Lebanon, Pa., highSchool=Mount Lebanon} FootballPlayer{number=28, position=S} Person{name=Matthew Baney, height=6'0", weight=225, hometown=State College, Pa., highSchool=State College} FootballPlayer{number=35, position=LB} Person{name=, height=0'0", weight=0, hometown=N/A, highSchool=N/A} FootballPlayer{number=0, position=N/A}

The Classes

App

it has the main method which is the method that Java looks for and runs to start any application

it creates 3 objects, one of the Model class, one of the View class and one of the Controller class.

When it creates Controller, it passes the two other objects as input parameters so that Controller has access to Model and View.

Model model = new Model(); View view = new View(); Controller controller = new Controller(view, model);

Controllerwill retrieve data from Model using the model object to call now the method getData ( )(previously called the method getData (int n))

getData without the "int n" parameter returns all objects in the ArrayList as Strings.

will pass the data to View, which will display it

no changes from the previous assignment

For instance, controller might look like this:

 view.basicDisplay(model.getData()); 

Model

it needs an updated method, loadData( ), to load the data, now using an ArrayList to store the 5 FootballPlayer objects

it needs a updated method, getData(), to handle FootballPlayer instead of Person

View

it just needs to display the text data that it will receive from Controller

no changes from the previous assignment

Personuses encapsulation

private attributes

a get and a set method for each attribute

has the following attributes

String name;

Height height;

int weight;

String hometown;

String highSchool;

has two constructors

one with no parameters

one with all the parameters (one for each attribute)

a toString( ) method

FootballPlayerhas the following attributes

int number;

String position;

two constructors one with no parametersuses the default values

number = 0

position = "N/A"

one with all the parameters (one for each attribute)

and a method

String toString( )

toString( ) overrides the superclass Object toString( ) method

toString( ) returns information about this class attributes as a String

Height

it is a class (or type) which is used in Person defining the type of the attribute height

uses encapsulation

private attributes

a get and a set method for each attribute

it has two attributes

int feet;

int inches

two constructors

one with no parameters

one with all the parameters (one for each attribute)

and a methodString toString( )

toString( ) overrides the superclass Object toString( ) method

toString( ) returns information about this class attributes as a String

it returns a formatted String with feet and inches

for instance: 5'2"

Output

The output will look like this:

Person{name=Marcus Allen, height=5'2", weight=200, hometown=Upper Marlboro, Md., highSchool=Dr. Henry A. Wise, Jr.} FootballPlayer{number=2, position=S} Person{name=Kyle Alston, height=5'9", weight=180, hometown=Robbinsville, N.J., highSchool=Robbinsville} FootballPlayer{number=37, position=CB} Person{name=Troy Apke, height=6'1", weight=220, hometown=Mt. Lebanon, Pa., highSchool=Mount Lebanon} FootballPlayer{number=28, position=S} Person{name=Matthew Baney, height=6'0", weight=225, hometown=State College, Pa., highSchool=State College} FootballPlayer{number=35, position=LB} Person{name=, height=0'0", weight=0, hometown=N/A, highSchool=N/A} FootballPlayer{number=0, position=N/A}
