Problème lancement Javafx (Exception in Application start method)
Bonjour :)
Devant mené un projet avec javafx, je décide de suivre un tutoriel de thenewboston afin d'apprendre à utiliser cette bibliothèque (https://www.youtube.com/watch?v=FLkO..._zwMw-&index=9)
Je fais tout comme indiquer dans la vidéo mais au moment de Run mon Main.java qui est le suivant:

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

Exception running application Main
Process finished with exit code 1 |
Pourriez-vous s'il plait m'aider à faire fonctionner cet exemple tout simple (mais que je ne suis pas capable de faire correctement :bug:) ?
Merci.
