Runtime Error displaying Linked List

Question

Hi, I've got a main class with a linked list which I am trying to display but I seem to be getting a "Class Cast Exception" eventhough I type cast the list as a String. Can anyone help please. The code is below:
import java.util.*;
public class Library
     public static void main (String[] args)
          LinkedList myList = new LinkedList();
          LibraryItems libraryItems = new LibraryItems("Java how to Program", 10);
          myList.add(libraryItems);
          ListIterator myListIterator = myList.listIterator();
          while (myListIterator.hasNext())
               String itemlist = (String) myListIterator.next();//this is where the runtime error occurs
               libraryItems = (LibraryItems) myList.getFirst();
               System.out.println(itemlist + " " + libraryItems.getItemName() + " "+
                                        libraryItems.getItemNumber());
}and here is the supporting class:
import java.util.LinkedList;
public class LibraryItems
     private String itemName;
     private int   itemNumber;
     public LibraryItems(String itemName, int itemNumber)
          this.itemName = itemName;
          this.itemNumber = itemNumber;
     public String getItemName()
          return itemName;
     public int getItemNumber()
          return itemNumber;
}Any help would really be appreciated.

Answer 1

You add LibraryItems to the LinkedList, but when you get them out, you are casting to String.
probably
LibraryItems itemlist = (LibraryItems) myListIterator.next();
System.out.println(itemlist.getItemName()...
