How to for each the hashmap? [duplicate]

Answer 1

I generally do the same as cx42net, but I don't explicitly create an Entry.

HashMap selects = new HashMap();
for (String key : selects.keySet())
{
    HashMap boxHolder = selects.get(key);
    ComboBox cb = new ComboBox();
    for (InnerKey innerKey : boxHolder.keySet())
    {
        cb.items.add(boxHolder.get(innerKey));
    }
}

This just seems the most intuitive to me, I think I'm prejudiced against iterating over the values of a map.
