Question

What I am supposed to do:

Add some necessary statements to the printOrderCost() method in the main class so that this method computes and p

Answer 1

From the code you have supplied, the getCost method "looks" fine

Your toString method should simply need to be appended to your return String s

public String toString()  // not necessary to format the output
{
    String s;
    s = brand + " ";
    s += quantity + " " ;
    s += itemCost + " ";
    s += getCost();
    return s;
}

You might also like to take a look at NumberFormat, which will allow you to control the output format, just in case you get a funny looking value ;)
