just adding two lines

Iterator<Integer> iterator = intList.iterator();
	while (iterator.hasNext()) {
	System.out.println(iterator.next());
	if(iterator.hasNext())
		iterator.next();
	}

List<Integer> intList = Arrays.asList(1, 2, 3, 4, 5, 6);

Iterator<Integer> iterator = intList.iterator();
int i = 1;
while (iterator.hasNext()) {
if (i % 2 != 0) {
System.out.println((Integer) iterator.next());
} else
iterator.next();
i++;
}

All the answers above are changing while loop while the question asks not to change while loop. I would rather implement iterable interface and override the next method to increment by 2 (after length check obviously) instead of incrementing by 1 which is the standard implementation.
