 public void start(Stage stage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("Sample.fxml")); //load the ui from fxml file
        
        Scene scene = new Scene(root); //A scene container
        
        stage.setScene(scene); //add the scene to stage
        stage.setTitle("My First JavaFX App"); //set the title of stage
        stage.setWidth(500); //width of stage
        stage.setHeight(500); //height of stage
