[Bluej-discuss] Ex.4.38

[Mike Stevens]

Hi Colleen,  I'm not getting it, am I using the right loop here?  I've tried
a for each loop also and have had no success.  I seems like when it hits my
if loop it just pass's it on by and does nothing.  I looked at the rest of
the exercises and have tried everything I can think of and it just won't add
item in.  I did create another method to add in just to test and the else
worked System.out.print("Id used");

Any help would be great.

 

public void addProduct(Product item)

    {

        

                Iterator it = stock.iterator();

            while(it.hasNext()) {

                Product inStock = (Product) it.next();

                if(inStock.getID() != item.getID())

                {

                    stock.add(item);

                }else{

                    System.out.print("Id used");

                }

        }

    }

 

 

 

 

Thanks

Mike
