using two iterators in one ArrayList

Question

Edit: Thank you for all your prompt replies. Now I see the assignment won\'t work. From another thread I read that iterator in Java is much less powerful than iterator in C+

Answer 1

Since you seem to be using lists, the simplest solution in your case is to use two indexes, something like this:

for (int i = 0; i < aList.size(); i++) {
  for (int j = i; j < aList.size(); j++) {
    // do stuff with aList's elements
    aList.get(j);
  }
}

With iterators, you can achieve similar things, but you have to construct new iterators for the inner loop, possibly from

aList.subList(i, aList.size()).iterator();
