I have an ArrayList<String> A that contains n elements, and an ArrayList<Integer> B that contains the indexes from A that I need to delete. How can I delete these indexes? After I remove an index like this : A.remove(index), then the size of A is smaller and the others indexes are not on the same position anymore.
Any idea is welcome.
You have to sort them (Collections.sort() probably works out of the box for integer arraylist), and start by removing the bigger index first.
