Shrinking an ArrayList to a new size

Question

Do I really need to implement it myself?

private void shrinkListTo(ArrayList list, int newSize) {
  for (int i = list.size() - 1; i >= newSi         


        

Answer 1

My solution :

public static void shrinkTo(List list, int newSize) {
    int size = list.size();
    if (newSize >= size) return;
    for (int i = newSize; i < size; i++) {
        list.remove(list.size() - 1);
    }
}

Just use :

shrinkTo(yourList, 6);
