JAVA FX

Whenever someone presses the letter "x" on the keyboard, your software should produce a specific "scrolling" effect for the entire interface. Each time the user presses "x", the scrolling will occur, regardless of which component the user is currently focused on. And there are two separate scenarios: one, where all x's pressed are visible on the interface, and two, where the x's pressed are not visible on the interface.

@Override public void start(Stage stage) throws Exception { stage.setTitle("Roll"); VBox root = new VBox();

List fields = new ArrayList(); for (int i=0; i<10; i++) { fields.add(new TextField()); } root.getChildren().addAll(fields); root.getChildren().add(new Button("Hello!"));

Scene scene = new Scene(root, 500, 300);

stage.setScene(scene); stage.show();
