public class JavaFX_NewWindow extends Application {
 
 @Override
 public void start(Stage primaryStage) {
 Button btn = new Button();
 btn.setText("New a Window");
 btn.setOnAction(new EventHandler<ActionEvent>() {
 @Override
 public void handle(ActionEvent event) {
 final Stage newStage = new Stage();
 Group newRoot = new Group();
 Scene scene = new Scene(newRoot, 300, 200);
 newStage.setScene(scene);
 newStage.show();
 
 VBox vBox = new VBox();
 
 Label newLabel = new Label();
 newLabel.setText(newStage.toString());
 
 Button btnClose = new Button("Close");
 btnClose.setOnAction(new EventHandler<ActionEvent>() {
 @Override
 public void handle(ActionEvent t) {
 newStage.close();
 }
 });
 
 vBox.getChildren().addAll(newLabel, btnClose);
 newRoot.getChildren().add(vBox);
 }
 });
 
 StackPane root = new StackPane();
 root.getChildren().add(btn);
 
 Scene scene = new Scene(root, 300, 250);
 
 primaryStage.setTitle("Hello World!");
 primaryStage.setScene(scene);
 primaryStage.show();

 public static void main(String[] args) {
 launch(args);
 }
