Sort an iterator of strings

Question

I have an iterator of strings.

For sorting i need to create a list from it and sort it using Collections.sort(list).

Is there any simple way t

Answer 1

Actually you cannot,as Iterator is not an Collection.

If it is obvious,you can do

public static Iterator sortedIterator(Iterator it, Comparator comparator) {
      List list = new ArrayList();
      while (it.hasNext()) {
          list.add(it.next());
      }

      Collections.sort(list, comparator);
      return list.iterator();
  }
}
