Question

Hello i have the issue that my programm is not working. I always get this console message in Intelij (Java):

/Users/samvolzke/Library/Mobile Documents/com~apple~CloudDocs/Documents/Programmieren/Java/Intelij Projects/Vocabeln/src/main/java/org/example/vocabeln/HelloController.java:3:14
java: Package javafx.event ist nicht sichtbar
(Package javafx.event wird in Modul javafx.base deklariert, das nicht im Moduldiagramm enthalten ist)

Has anybody an idea why the program do not work?

Hear are my classes:

    }

    @FXML
    void ConfirmUserName(MouseEvent event) {

    }

    @FXML
    void CreateAccount(ActionEvent event) {

    }
    void createAccount(ActionEvent event) {
        try {
            FXMLLoader loader = new FXMLLoader(getClass().getResource("/org/example/vocabeln/CreateAccount.fxml"));
            Parent root = loader.load();

            Stage currentStage = (Stage)((Hyperlink)event.getSource()).getScene().getWindow();
            currentStage.close();
        }
        catch (Exception e){
            e.printStackTrace();
