Question
Assume the following method is within the KWLinkedList class, what does the following method do?
public void undefined(E item)
{
Listiterator<E> iter1 = iterator( );
Listiterator<E> iter2 = iterator(1);
if (Iter1.hasNext() && iter2.hasNext()
{
if( iter1.next().equals (iter2.next())
iter2.add(item);
}
}
2. It checks the first two consecutive elements of the list, if equal, it inserts "item" at the end of the list.
b. It checks the first two consecutive elements of the list, if equal, it inserts "item" before the first element.
O .It checks the first two consecutive elements of the list, if equal, it inserts “item" in between them.
O d.lIt checks the first two consecutive elements of the list, if equal, it inserts "item" after the second element.
