Bonjour

Devant mené un projet avec javafx, je décide de suivre un tutoriel de thenewboston afin d'apprendre à utiliser cette bibliothèque (

)

Je fais tout comme indiquer dans la vidéo mais au moment de Run mon Main.java qui est le suivant:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
 
public class Main extends Application { // get functions for javafx
 
    public static void main(String[] args) {
        launch(args); // set up program as a javafx application
    }
 
    @Override
    public void start(Stage primaryStage) throws Exception { // main javafx code
        primaryStage.setTitle("Title of the window"); // set the window title
 
        Button button = new Button(); // create a button
        button.setText("Click me");
 
        StackPane layout = new StackPane(); // create a layout
        layout.getChildren().add(button); // add the button into the layout
 
        Scene scene = new Scene(layout, 300,255); // create a new scene
        primaryStage.setScene(scene); // add the scene to the Stage
        primaryStage.show(); // display
    }
}
 
/*
*
* the Stage is the windows
*
* the Scene is the content inside of the window
*

Seulement dans le tutoriel, une fenêtre apparait alors que moi IntelliJ, maffiche:

Exception running application Main

Pourriez-vous s'il plait m'aider à faire fonctionner cet exemple tout simple (mais que je ne suis pas capable de faire correctement ) ?

Merci.
