'List.remove()' called in loop

Reports List.remove(index) called in a loop that can be replaced with List.subList().clear().

The replacement is more efficient for most List implementations when many elements are deleted.

Example:

void removeRange(List<String> list, int from, int to) {
  for (int i = from; i < to; i++) {
      list.remove(from);
  }
}

After the quick-fix is applied:

void removeRange(List<String> list, int from, int to) {
  if (to > from) {
    list.subList(from, to).clear();
  }
}

The quick-fix adds a range check automatically to prevent a possible IndexOutOfBoundsException when the minimal value is bigger than the maximal value. It can be removed if such a situation is impossible in your code.
