Answer 1

Create a new class as follows:

public class OtherClass {
        
    @FXML
    private AnchorPane Accueil;

    @FXML
    private AnchorPane Sport;

    public void entree() {
        Accueil.setVisible(false);
        Sport.setVisible(true);
    }
}

Now in your main method you need to create an object of such class so that you can call the method:

public static void main(String[] args) {
    OtherClass otherClass = new OtherClass();
    otherClass.entree();
}

As a side note, in Java, the standard is to have method names following snakeCase , so it should be entree() instead.
