Write a method that removes all but the first two elements from a linked list, using an iterator. You may assume that the list has at least two elements.

Complete the following file:

LinkedListUtil.java

import java.util.LinkedList; import java.util.ListIterator; public class LinkedListUtil { /** deletes all but the first two linked list enries */ public static void processList(ListIterator iter) { // Your work here } // This method is used to check your work public static LinkedList<String> check(String[] values) { LinkedList<String> list = new LinkedList<String>(); for (String s : values) list.add(s); processList(list.listIterator()); return list; } }
