The Build button displays after you click in a field property box so you can further define the property

Analyze the following code:

``` import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.layout.HBox; import javafx.scene.layout.Pane; import javafx.geometry.Insets; import javafx.stage.Stage; import javafx.scene.image.Image; import javafx.scene.image.ImageView; public class Test extends Application { @Override // Override the start method in the Application class public void start(Stage primaryStage) { // Create a pane to hold the image views Pane pane = new HBox(10); pane.setPadding(new Insets(5, 5, 5, 5)); Image image = new Image("www.cs.armstrong.edu/liang/image/us.gif"); pane.getChildren().addAll(new ImageView(image), new ImageView(image)); // Create a scene and place it in the stage Scene scene = new Scene(pane); primaryStage.setTitle("ShowImage"); // Set the stage title primaryStage.setScene(scene); // Place the scene in the stage primaryStage.show(); // Display the stage } /** * The main method is only needed for the IDE with limited * JavaFX support. Not needed for running from the command line. */ public static void main(String[] args) { launch(args); } } ``` a. The program runs fine and displays two images. b. new Image("www.cs.armstrong.edu/liang/image/us.gif") must be replaced by new Image("http://www.cs.armstrong.edu/liang/image/us.gif"). c. The image object cannot be shared by two ImageViews. d. The addAll method needs to be replaced by the add method.
