Solve using java

Assume the following method is outside the class of KWArrayList class but has access to the methods of KWArrayList class, what
does it do?
public static void Unknown(KWArrayList<Integer> list1, KWarrayList<Integer> list2)
{
if (list1.size() == 0 || list2.size() ==0) return;
int loop;
if (list1.size() < list2.size())
loop= list1.size();
else loop= list2.size():
for (int i=0; i<loop; i++)
list1.set(i.(Integer) list1.get(i) + (Integer) list2.get(i))
It changes the elements of list1 as each element in list1 would be the summation of the old value in list1 with the
A
corresponding value in list 2 based on the size of the larger list, list1 or list2.
It changes the elements of list1 as each element in list1 would be the summation of the old value in list1 with the
B
corresponding value in list 2 based on the size of the smaller list, list1 or list2.
It changes the elements of list1 as each element in list1 would be the summation of the old value in list1 with the
corresponding value in list 2 based on list2 size.
It changes the elements of list1 as each element in list1 would be the summation of the old value in list1 with the
corresponding value in list 2 based on list1 size.
