Mixed up

Question

I already posted this message, but i realized it wasn't explained very well, it was confusing. So forgive me to post it again, but better explained:
I have objects from a class i made myself, Product. This class has an ArrayList called list.
Here is a bit of code:
Product parent = new Product();
res = stat.executeQuery(sql);
while(res.next())
          child.setIdentifier(res.getInt("IDENTIFIER"));
          child.setStringId(res.getInt("STRINGID"));
          (parent.list).add(child);                         
          System.out.println("Child of " + parent.getIdentifier() + ": " + child.getIdentifier());
Here everything is fine. i get these values with the System.out.println(...):
Child of a : 222
Child of b : 243
Child of b : 543
Child of b: 469
which is what i wanted.
BUT, when i try to do this:
for(Iterator it = (parent.list).iterator();it.hasNext();)
     Product d = new Product();
     d = (Product) it.next();
     System.out.println("d = " + d.getIdentifier());
the output i get is this:
469
469
469
469
when i should be getting
222
243
543
469
why is it stuck to the last value entered??
....this is weird!!!!!
Can anyone help me please?
Thanks for your patience :)

Answer 1

You need a new child object every time, else you end up changing the same child object the next time through the loop. I assume that is what you found. Also no need for new object here, just do it like so
for(Iterator it = (parent.list).iterator();it.hasNext();)
  Product d = (Product) it.next();
  System.out.println("d = " + d.getIdentifier());
}
