How do I get a keyIterator for a LinkedHashMap?

Question

By looking at the source code for LinkedHashMaps from Sun, I see that there is a private class called KeyIterator, I would like to use this. How can I gain access?

Answer 1

It's a private class, so you can't directly use it.

  private class KeyIterator extends LinkedHashIterator {

An instance of it is returned when you use the normal Iterator.

myMap.keySet().iterator()
