JavaFX Model View Controller:

Find a way to access building data I put a static ArrayList to store the buildings, a method to get all buildings (load), and a method to return a single building based on the indices of that building in my Building class:

// this is static member of the building class

public static ArrayList buildings = new ArrayList<>();

// this is just the signature, take code from your previous project to read the file and load an ArrayList of Buildings... public static ArrayList load() throws FileNotFoundException {

... put your code here to read file...

}

//signature of method to return one building, this should not be called until load is called..

public static Building getBuilding(int indicies)

{

...return the building at the certain index passed in

}

Though I used my Building class, you can create a singleton to hold data as learned in Beginning Java

Write a UI (JavaFX with material learned in Chapters 14-16) to create a UI similar to the pictures below:

Where the information on the right shows up for the building chosen on the left. Use a ListView control, and do not have multiple selection set as an option (just one at a time).

Spruce up your design.

TIPS:

1. Inside the listener for the ListView, I used this line to find the index:

int index = buildingListView.getSelectionModel().getSelectedIndex();

2. I then called my method to get the building object to populate my UI

example:

Building b = Building.getBuiding(index);

Then, the name is b.getName(); the picture is b.getImageName(); etc.

3. Building text:

CRITERIA POINTS

Create appropriate back - end of application (this is the Building application

including Building, Coordinate, InvalidLatitude, InvalidLongitude, etc)this

is basically the last version of the app, with the main program removed an another way to read the file, store a list of buildings and also to return a single building. This can be

accomplished in the Building class as described above (and in video) or in a

singleton class designed just to hold data (Model)

Create appropriate UI Use JavaFX without FXML to show a ListView of building names

and then show the detail of each building as they are chosen one at a time. Your design

can be as desired so long as it contains attributes and images from a building object -

you can use one view like shown OR create another JavaFx Window or AlertBox as long as it is professional

All code must compile and work and have the architecture described.

Back-end of application:

public class Main {

public static void main(String args[]) throws FileNotFoundException, InvalidLatitudeException, InvalidLongitudeException {

File fileInput = new File("src/BuildingData.txt");

Scanner sc = new Scanner(fileInput);

// Array list to hold buildings

ArrayList list = new ArrayList<>();

// while loop to read data into variables

while (sc.hasNextLine()) {

String campus = sc.next();

String name = sc.next();

double latitude = Double.parseDouble(sc.next());

double longitude = Double.parseDouble(sc.next());

String imageName = sc.next();

String buildingCode = sc.next();

// Instantiate building object using constructor

try {

Building buildingObject = new Building(campus, name, latitude, longitude, imageName, buildingCode);

if (latitude >= 34 && latitude <=36) {

if (longitude >= -80 && longitude <= 78)

// Adding Building to Array list

list.add(buildingObject);

for (int i = 0; i < 1; i++) {

System.out.println(buildingObject.toString());
