J'ai mon programme presque terminé où ils sont trois classes: une classe de conducteur, une classe de pizza, et une classe de commande qui calcule le prix de la commande. Mon seul problème est une fois que j'exécute mon code les variables passeront par la boucle while dans la méthode inputToppings de la classe pizza et imprimeront les bonnes valeurs quand la méthode toString sera appelée dans la classe pizza de la classe de commande mais dans ma méthode getToppingQuantity il transmet les valeurs par défaut pour les variables d'instance. Où vais-je me tromper ici?variables retournant à la valeur par défaut

comme je l'ai dit mon programme passe par les étapes correctement, mais renvoie la valeur erronée pour les variables Topping dans la méthode getToppingQuantity (Remarque: je n'ai pas inclus la classe client car elle ne correspond pas à mon numéro actuel)
