Does using an Iterator over a TreeMap in Java interfere with the order of keys?

Question

I want to know that if using an Iterator over a TreeMap in Java interfere with the order of keys?

Solution

No - it will iterate in the order defined by the TreeMap, i.e. the natural ordering of the keys, or the one imposed by the comparator specified in the constructor. Just iterating won't change that in the underlying tree map, either.
