I am currently learning about LinkedList, and need help completing these few questions to make sure I am doing them correct. Any help is appreciated, and I will leave a positive review!

Programs Needed to complete these questions -

ListNode:

public class ListNode implements Linkable { private Comparable listNodeValue; private ListNode nextListNode; public ListNode() { listNodeValue = null; nextListNode = null; } public ListNode(Comparable value, ListNode next) { listNodeValue=value; nextListNode=next; } public Comparable getValue() { return listNodeValue; } public ListNode getNext() { return nextListNode; } public void setValue(Comparable value) { listNodeValue = value; } public void setNext(Linkable next) { nextListNode = (ListNode)next; } }

Linkable:

public interface Linkable { Comparable getValue(); Linkable getNext(); void setNext(Linkable next); void setValue(Comparable value); }

1. What order would the values go in the boxes below?

2. What order would the values go in the boxes below?

3. Complete method countOdds().

4. Complete method skipEveryOther().

5. Complete method doubleUp().

6. Complete method countNodes().

7. Complete method doubleFront().

ListNode front = null, back = null; for (int i=0; i 5 -> 3 -> 4 -> 7 -> null //list after call to skip 1 -> 3 -> 7 -> null \/method doubleUp will double the size of the list by adding in lew nodes with the same values as the original list nodes public void doubleUp (ListNode list) Example 1/original list 1 -> 4 -> null //list after call to double 1 -> 1 -> 4 -> 4 -> null private ListNode theList; //instance variable / data field //method countNodes will count the number of nodes present in the list public int countNodes () { Example //original list 1 -> 5 -> 3 -> 4 -> 7 -> null //retun value of countNodes 5 } private ListNode theList; //instance variable / data field Example l/method doubleFront will add a new node at the front of the list with // the same value as the current node at the front of the list public void doubleFront () { //original list 1 - 4 -> null } //list after call to double 1 -> 1 - 4 -> null private ListNode theList; //instance variable Example 1/method removeNode will remove the 1" occurrence of obj public void removeNode (Object obj) { 1/original list 1 -> 5 -> 3 -> 4 -> 7 -> null //value to remove 5 1/original list after remove 1 -> 3 -> 4 -> 7 -> null
