Auf Thema antworten

Ich mache einen Online kurs bei Udemy und wir sollen diesen Code verwenden. Im Video funktioniert das auch wundervoll. Ich Tippe diesen Code ab und mache dabei etwas verkehrt, ich habe schon andere Programme aus dem Kurs Problemlos hergestellt nur bei diesem hargt es irgendwo. Da ich hier schon mal sehr nette Hilfe bekommen habe. Wollte ich einmal nachfragen ob jemand sieht wo mein Fehler ist, ich habe schon probiert den Code für das hinzufügen zu ändern nur daran scheint es nicht zu liegen.

Ich weiß nicht so genau was damit gemeint das im Constructor ein Fehler ist, in der Ide ist nichts fehlerhaft angezeigt die Exception kommt erst beim Ausführen





package application;


import javafx.application.Application;

import javafx.scene.Group;

import javafx.scene.Scene;

import javafx.scene.image.Image;

import javafx.scene.image.ImageView;

import javafx.stage.Stage;


public class Main extends Application {


    final String[] Icon = {

            "firefox",

            "eclipse",

            "mail",

            "textedit",

           

    };

   


    @Override

    public void start(Stage primaryStage) throws Exception {

        Group root = new Group();

       

        //Dock erstellen

        ImageView imageViewDock = new ImageView(new Image("dock.png"));

       

        root.getChildren().add(imageViewDock);

       

        //Scene

        Scene scene = new Scene(root,500,200);

        primaryStage.setScene(scene);

        primaryStage.show();

    }

       

       

        public static void main(String[] args) {

        launch(args);


   

    }


}
