Fill in the blanks in the below code implementing a LinkedList class. In this question you will be completing a constructor, a for loop, a while loop, and a recursive function.

public class LinkedList { private Node first; private class Node { public int data; public Node next; public Node(int data, Node next) {

 } } // returns the size of the linked list (recursive) public int size() { 

return

 } // recursive helper function 

private int size(

) {

 // base case 

 } // returns an array that has the same data as this linked list // list[0] = first.data, etc. public int[] toArray() { int[] list = new int[size()]; int i = 0; 

for (

) {

 } return list; } // returns the sum of the numbers in the linked list public int sum() { int s = 0; 

while (

) {

 } return s; }
