Here are the 2 get methods that I have.
thanks again for all the help.
public int getNumProducts() {
return numProducts;
}
public int getNumProducts(int index)
{
if(this.results== null)
{
this.results = new ArrayList();
}
while(index >= this.results.size())
{
this.results.add(new Product());
}
Product p = (Product) results.get(index);
return p.getNumProducts();
}
