Java program that creates a photo album application. Which will load a collectio

Question

Java program that creates a photo album application.    Which will load a collection of images and displays them in a album layout. The program will allow the user to tag images with metadata:

•Title for the photo

.      Limited to 100 characters.

•Description for the photo

. Limited to 300 characters.

•Date taken

•Place taken

Functional Specs

1.Your album should be able to display the pictures sorted by Title, Date, and Place.

2.When the user clicks on a photo, data should be displayed.

3.The user should be able to add or remove pics.

*Please note the swing library cannot be used only scene (vBox,hBox, etc...)

*This is what I have so far - I can display and select images but Im not sure how to apply the buttons to remove pic, add pic, and add data (title, date, place) Someone tried to explain, but I really just got more confused. please provide import classes so I can have a better understanding of where everything is coming from.

public class PhotoAlbum extends Application {

    Stage stage;

    @Override
    public void start(Stage primaryStage) throws Exception {
        stage = primaryStage;
        ScrollPane root = new ScrollPane();
        TilePane tile = new TilePane();
        root.setStyle("-fx-background-color: DAE6F3;");
        tile.setPadding(new Insets(15, 15, 15, 15));
        tile.setHgap(15);

        String path = "src/image/";

        File folder = new File(path);
        File[] listOfFiles = folder.listFiles();

        for (final File file : listOfFiles) {
                ImageView imageView;
                imageView = createImageView(file);
                tile.getChildren().addAll(imageView);
        }

        root.setHbarPolicy(ScrollPane.ScrollBarPolicy.NEVER); // Horizontal
        root.setVbarPolicy(ScrollPane.ScrollBarPolicy.AS_NEEDED); // Vertical scroll bar
        root.setFitToWidth(true);
        root.setContent(tile);

        primaryStage.setWidth(Screen.getPrimary().getVisualBounds().getWidth());
        primaryStage.setHeight(Screen.getPrimary().getVisualBounds()
                .getHeight());
        Scene scene = new Scene(root);
        primaryStage.setScene(scene);
        primaryStage.show();

    }

    private ImageView createImageView(final File imageFile) {
        // DEFAULT_THUMBNAIL_WIDTH is a constant you need to define
        // The last two arguments are: preserveRatio, and use smooth (slower)
        // resizing

        ImageView imageView = null;
        try {
            final Image image = new Image(new FileInputStream(imageFile), 150, 0, true,
                    true);
            imageView = new ImageView(image);
            imageView.setFitWidth(150);
            imageView.setOnMouseClicked(new EventHandler<MouseEvent>() {

                @Override
                public void handle(MouseEvent mouseEvent) {

                    if(mouseEvent.getButton().equals(MouseButton.PRIMARY)){

                        if(mouseEvent.getClickCount() == 2){
                            try {
                                BorderPane borderPane = new BorderPane();
                                ImageView imageView = new ImageView();
                                Image image = new Image(new FileInputStream(imageFile));
                                imageView.setImage(image);
                                imageView.setStyle("-fx-background-color: BLACK");
                                imageView.setFitHeight(stage.getHeight() - 10);
                                imageView.setPreserveRatio(true);
                                imageView.setSmooth(true);
                                imageView.setCache(true);
                                borderPane.setCenter(imageView);
                                borderPane.setStyle("-fx-background-color: BLACK");
                                Stage newStage = new Stage();
                                newStage.setWidth(stage.getWidth());
                                newStage.setHeight(stage.getHeight());
                                newStage.setTitle(imageFile.getName());
                                Scene scene = new Scene(borderPane,Color.BLACK);
                                newStage.setScene(scene);
                                newStage.show();
                            } catch (FileNotFoundException e) {
                                e.printStackTrace();
                            }

                        }
                    }
                }
            });
        } catch (FileNotFoundException ex) {
            ex.printStackTrace();

        return imageView;
