Warum bin ich immer die Fehlermeldung "die Methode Ist nicht definiert für den Typ"?

Lerne ich die Grundlagen an der Universität und möchte einige helfen mit die folgende Fehlermeldung von Eclipse : "Die Methode getCost() ist nicht definiert für den Typ 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)

Hier ist mein code

public class ShopCLI {

        int choice = sc.nextInt();

        System.out.println("Please Choose an Outer From the List: ");
        System.out.println("Press 1 to Continue or 2 to Exit");
        int Sandwich = sc.nextInt();

        System.out.println("Outer Options are Bun, Bread or Brioche");

        String inputOuter = sc.next();
