I have a code below where i tried to copy an arrayList to listusing Collections.copy method.
I am getting IndexOutofBoundsException since the size of destination list is not equal to the source list.

my question.. is there any Java API help through which i can copy an entire list of any size to a new list(the destination list can be of any size and may be empty).

Even simpler:

List list=new ArrayList(arrayList);
