My GUI will not show up even when the program is running. t

Question

[enter image description here][1]Here is the Driver , The program will run with no errors but the gui will not show up at all. I am a noob to FX and i am just trying to get it to work.

public class Vacation extends Application {
private Stage stage;

 @Override
public void start(Stage stage) throws Exception {
  this.stage = stage;
  try{
    FXMLLoader loader = new 
FXMLLoader(getClass().getResource("Vacation.fxml"));
    AnchorPane pane = loader.load();

    MainControler mainController = loader.getController();
    Scene scene = new Scene(pane, 640, 450);
    stage.setScene(scene);
    stage.show();

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

    }
}

Here is the FXML.

and here is the Controller.

public class MainControler implements Initializable {

     @FXML
   private Button DC;

    @FXML
    private Button STB;

    @FXML
    private Button SDC;

    @FXML
    private Button BC;


   @FXML public void BCButtonpress(ActionEvent event) {
try{
    FXMLLoader bcLoader = new 
FXMLLoader(getClass().getResource("BaronCliff.fxml"));
    Parent root1 = (Parent) bcLoader.load();
    Stage bc = new Stage();
    bc.setTitle("Baron Cliff");
    bc.setScene(new Scene(root1));
    bc.show();

}catch (IOException e){
    System.out.println("Cant Load new Window.");
}
}


  @FXML  public void DCbuttonpress(ActionEvent event) {
try{
    FXMLLoader bcLoader = new 
FXMLLoader(getClass().getResource("DevilsCourthouse.fxml"));
    Parent root1 = (Parent) bcLoader.load();
    Stage bc = new Stage();
    bc.setTitle("Devils Courthouse");
    bc.setScene(new Scene(root1));
    bc.show();

}catch (IOException e){
    System.out.println("Cant Load new Window.");
}
}


  @FXML  public void STBbuttonPress(ActionEvent event) {
 try{
    FXMLLoader bcLoader = new 
    FXMLLoader(getClass().getResource("Scuba.fxml"));
    Parent root1 = (Parent) bcLoader.load();
    Stage bc = new Stage();
    bc.setTitle("Scuba the Bahamas");
    bc.setScene(new Scene(root1));
    bc.show();

}catch (Exception e){
    System.out.println("Cant Load new Window.");
}
}


    @FXML public void SDC(ActionEvent event) {
 try{
   FXMLLoader bcLoader = new 
 FXMLLoader(getClass().getResource("Skydive.fxml"));
   Parent root1 = (Parent) bcLoader.load();
   Stage bc = new Stage();
   bc.setTitle("Skydive Colorado");
   bc.setScene(new Scene(root1));
   bc.show();

  }catch (Exception e){
   System.out.println("Cant Load new Window.");
   }
    }

Thanks in advance for any help, I finally broke down and decided to post this, i could not find anyone with my problem probably something minor but i have no one with fresh eyes to really give it a look. apologies.

After putting in the e.printStackTrace(); in the catch block I got a list of exceptions.

  javafx.fxml.LoadException: Error resolving

here is the typo fixed.

<Button fx:id="DC" layoutX="229.0" layoutY="53.0" mnemonicParsing="false" 
 onAction="#DCbuttonpress" text="Devils CourtHouse" textFill="#ee0707" 
 />enter

here is the exception after running after the fix.

Don't squash exceptions. If anything is going wrong, you won't know about it. At a minimum, put `e.printStackTrace();` inside your `catch` block (in your `start()` method). If you get a [stack trace](https://stackoverflow.com/q/3988788/2775450), include it in its entirety (format it as code) in the question. — James_D, Apr 27 '18 at 03:09
fixed the typo, triple checked and it is throwing the same exception at me. — Jake Haynes, Apr 27 '18 at 03:21
The *same* exception? If you fixed that typo, it must at least throw a different exception. — James_D, Apr 27 '18 at 03:27
Lordy, thank you, I had an import for the controller but it was not the correct ones. Apologies, i have been working on this for a while now. Thank you very much! — Jake Haynes, Apr 27 '18 at 03:44
unrelated: please learn java naming conventions and stick to them — kleopatra, Apr 27 '18 at 07:42

The stack trace:

javafx.fxml.LoadException: Error resolving 
               onAction='#DCbuttonPpess', either the event handler is 
            not in the Namespace or there is an error in the script.

   file:/C:/Users/Kalamar/Documents/NetBeansProjects/Vacation/di 
       st/run201542084/Vacation.jar!/Application/Vacation.fxml:17

Indicates that there is a problem with the onAction handler specified at line 17 of the Vacation.fxml file. That line is:

<Button fx:id="DC" ... onAction="#DCbuttonPpess" ... />

There is a clear typo in the onAction attribute: the method defined in the controller class is

@FXML public void DCbuttonpress(ActionEvent event) {
    /* ... */
}

So the FXML should be

<Button fx:id="DC" ... onAction="#DCbuttonpress" ... />

My GUI will not show up even when the program is running. t
