Assume thát the following method is in a class called DLL (not s ame as KWLinkedList). What does this method do? public void method_LI( ) { KWLinkedList list = new KWLinkedList( ); list.add(2); list.add(-1); list.add(0); list.add(1); list.add(0); Listlterator iter = list.listiterator(); while(iter.hasNext()) { if (iter.next() 0) == iter.remove(); } if( iter.hasPrevious()) System.out.println("END"); else while(iter.hasNext()) System.out.print(iter.next() + " "); }

-
Removes the nodes having 0 as its data and prints 2 -1 1
-
Prints 2 -1 0 1 0 without removing anything.
-
Removes the nodes having 0 as its data and prints END.
-
