Can I change List<Integer> to int[]?

I'm learning Java. Can I change the list to int[]? There is a method called List.toArray(), but the return data type is Object[]. I want to get an Integer[] or an int[] What should I do? Right now, I'm just turning the repetitive sentences and putting them in one by one. Is there a better way?

int[] toIntArray(List<Integer> list){
  int[] ret = new int[list.size()];
  for(int i = 0;i < ret.length;i++)
    ret[i] = list.get(i);
  return ret;
}
