Error in scene in Java FX - javafx-8

Question

I'm new to javaFX 8 and working with a simple project, but im having some issues with scene.
I get this error:
Error:(35, 25) java: method getScene in class javafx.stage.Window cannot be applied to given types;
required: no arguments
found: javafx.scene.Scene
reason: actual and formal argument lists differ in length
And this is the code:
package ch.makery.address;
import java.io.IOException;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class MainApp extends Application{
private Stage primaryStage;
private BorderPane rootLayout;
#Override
public void start(Stage primaryStage) {
this.primaryStage = primaryStage;
this.primaryStage.setTitle("AddressApp");
initRootLayout();
showPersonOverview();
}
public void initRootLayout() {
try {
FXMLLoader loader = new FXMLLoader();
loader.setLocation(MainApp.class.getResource("view/RootLayout.fxml"));
rootLayout = (BorderPane) loader.load();
Scene scene = new Scene(rootLayout);
primaryStage.getScene(scene);
primaryStage.show();
}catch (IOException e) {
e.printStackTrace();
}
}
public void showPersonOverview() {
try {
FXMLLoader loader = new FXMLLoader();
loader.setLocation(MainApp.class.getResource("view.Personview.fxml"));
AnchorPane personOverview = (AnchorPane) loader.load();
rootLayout.setCenter(personOverview);
}catch (IOException e) {
e.printStackTrace();
}
}
public Stage getPrimaryStage() {
return primaryStage;
}
public static void main(String[] args) {
launch(args);
}
}
Thanks in advance.
