TableView not displaying data

I am trying to get this table view to work, but for some reason, when I run the program, the table is empty. I compared it several times with the example given in the Oracle and the Youtube tutorial, but I cannot figure out what I am missing.

The code compiles without errors. Here it is:

public class JavaFXcourseNewBoston extends Application {



Stage window;

TableView<Person> table;



public static void main(String args) {

    launch(args); // übernimmt den String args aus main      

}



@Override

public void start(Stage ersteStage) throws Exception {

    window = ersteStage;

    window.setTitle("Tables!");



    // public Person(String fName, String lName, int age)

    //TableColumn first name

    TableColumn<Person, String> fnameC = new TableColumn<>("Name");

    fnameC.setMinWidth(100);

    fnameC.setCellValueFactory(new PropertyValueFactory<>("fName"));



    //TableColumn last name 

    TableColumn<Person, String> lnameC = new TableColumn<>("Last Name");

    lnameC.setMinWidth(100);

    lnameC.setCellValueFactory(new PropertyValueFactory<>("lName"));



    //TableColumn age

    // WRAPPER NOT PRIMITIVE DATA TYPES!! 

    TableColumn<Person, Integer> ageC = new TableColumn<>("Age");

    ageC.setMinWidth(50);

    ageC.setCellValueFactory(new PropertyValueFactory<>("age"));



    table = new TableView<>();

    table.setItems(getP());

    table.getColumns().addAll( fnameC, lnameC, ageC); 



    VBox vbox = new VBox();

    vbox.getChildren().addAll(table);



    //initialize window

    Scene scene = new Scene(vbox, 300, 250);

    window.setScene(scene);

    window.show();

}



public ObservableList<Person> getP() {

    ObservableList<Person> persons = FXCollections.observableArrayList();

    persons.add(new Person("Lisa", "Simpson", 10));

    persons.add(new Person("Bart", "Simpson", 12));

    persons.add(new Person("Marge", "Simpson", 32));

    persons.add(new Person("Homer", "Simpson", 35));

    persons.add(new Person("Maggie", "Simpson", 2));



    return persons;

}



}// end class

And the Person class:

public class Person {



String fName;

String lName;

int age;



Person(String fName, String lName, int age) 

{

    this.fName = fName;

    this.lName = lName;

    this.age = age;                  

}

}

(I didn't write any getters and setters for Person since they aren't needed here.)

I have been trying to solve this for 2 hours (yes, really) and would greatly appreciate any help.
