Hi Nima,
You can't modify your list using iterator, because it changes the
state and the iterator "gets confused", so you're getting the
exception. If you want to populate the list, do a simple loop and
invoke add(Object) method. Use iterator only to read list content, or
update objects stored in the list, but do not change list's state
while traversing the iterator.
