Pourquoi j'obtiens le message d'erreur “la Méthode n'Est pas définie pour le type”?

Je suis en train d'apprendre les bases à l'Université et voudrais un peu d'aide avec l'erreur suivante à partir de l'Éclipse : "La méthode getCost() n'est pas défini pour le type ShopCLI" &

"Exception in thread "main" java.lang.Error: Unresolved compilation problem:
    The method getCost() is undefined for the type ShopCLI
    at components.ShopCLI.main(ShopCLI.java:39)
