Clone an Iterator in Java?

Question

In a game I have a list of players, let\'s say like this:

LinkedList players = new LinkedList();

I want to let

Answer 1

The following will do it:

ListIterator i1 = players.listIterator(0);
while (i1.hasNext()) {
    String p1 = i1.next();
    ListIterator i2 = players.listIterator(i1.nextIndex());
    while (i2.hasNext()) {
        String p2 = i2.next();
        System.out.println("Interact: " + p1 + ", " + p2);
    }
}

It relies on the ListIterator's ability to start from the given position and to also know its current position.
