iteration

In java if I am looping over the keySet() of a HashMap, how do I (inside the loop), get the numerical index of that key?

Basically, as I loop through the map, I want to be able to get 0,1,2...I figure this would be cleaner than declaring an int and incrementing with each iteration.

Thanks.
