How to get the current loop index when using Iterator ?

Question

greetings all i am using an Iterator to iterate through collection and i want to get the current loop index any ideas how to do that ?

Answer 1

Use an int and increment it within your loop.

Answer 2

Use your own variable an increment it in the loop.

Answer 3

What kind of collection? If it's an implementation of the List interface then you could just use (it.nextIndex()-1).

Answer 4

Use a ListIterator to iterate through the Collection. If the Collection is not a List to start with use Arrays.asList(Collection.toArray()) to turn it into a List first.
