Need help filling in the areas, unsure of how to do the code, JAVA. I've highlited what needs completing. 

/** Example from R15.1. Explain what the following code prints. Draw pictures of the linked list after each step. Just draw the forward links, as in Figure 1. Add a static method that returns a string representation of the list in the form: list string version [] / [A] A -> / [A,B] A -> B -> / etc. The expected output is: A -> / B -> A -> / C -> B -> A -> / C B -> A -> / B A -> / A / */ import java.util.LinkedList ; import java.util.Scanner ; public class LinkedListTester1 { public static void main(String[] args) { LinkedList list = new LinkedList() ; list.addFirst("A") ; System.out.println(toString(list)) ; list.addFirst("B") ; System.out.println(toString(list)) ; list.addFirst("C") ; System.out.println(toString(list)) ; System.out.println(list.removeFirst()) ; System.out.println(toString(list)) ; System.out.println(list.removeFirst()) ; System.out.println(toString(list)) ; System.out.println(list.removeFirst()) ; System.out.println(toString(list)) ; } /** A static method that gives a string representation of a linked list in the form: list string version [] / [A] A -> / [A,B] A -> B -> / etc. @param list the linked list of type LinkedList @return a string representation like A -> B -> / */ //-----------Start below here. To do: approximate lines of code = 6 // 0. the signature of the method //initialize result //for each element in the list //append the element and arrow //append the / //return the result  //-----------------End here. Please do not remove this comment. Reminder: no changes outside the todo regions. }
