iterator
public final Iterator<Map.Entry<K,V>> iterator()
- Returns a "weakly consistent" iterator that will never
throw
ConcurrentModificationException
, and
guarantees to traverse elements as they existed upon
construction of the iterator, and may (but is not
guaranteed to) reflect any modifications subsequent to
construction.

in interface Set<Map.Entry<K,V>>
- Returns:
- an iterator over the entries of this map
