Answer 1

Your code looks fine to me. To call getCost() in toString() method, simply just call it with getCost().

So your toString() method should be something like this:

public toString(){
    String s;
    s = brand + " ";
    s += quantity + " " ;
    s += itemCost + " ";
    s += getCost();

    return s;
}

Hope this is what you're looking for :)
