Question 5

Assume that the following method is in a class called DLL (not same as KWLinkedList). What does this method do?

 

public void method_LI( )

{

KWLinkedList<Integer> list = new KWLinkedList<Integer>( );

list.add(2);

list.add(-1);

list.add(0);

list.add(1);

list.add(0);

ListIterator<integer> 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 END.


Removes the nodes having 0 as its data and prints 2 -1 1


Removes the nodes having 0 as its data and prints 1 -1 2


Prints 2 -1 0 1 0 without removing anything.

Question 5 1.5 Points Assume that the following method is in a class called DLL (not same as KWLinkedList). What does this method do? public void method_LI() { KWLinkedList<Integer> list = new KWLinkedList<Integer>( ); list.add(2); list.add(-1): list.add(0): list.add(1): list.add(0): Listiterator<integer> iter = list.listiterator(); while(iter.hasNext() { if (iter.next() == 0) iter.remove(); } if( iter.hasPrevious(0) System.out.println("END"); else while(iter.hasNext()) System.out.print(iter.next() + " "); } A Removes the nodes having 0 as its data and prints END. B Removes the nodes having 0 as its data and prints 2-1 1 c) Removes the nodes having 0 as its data and prints 1-12 Prints 2-1010 without removing anything.
