I need some help with java LinkedLists ... i can't get this code to work.. i'm trying to do a method to creat a list and print it :(

public class ItemLinkedList
{
	private Item myData; 

	private ItemLinkedList myNext; 
	
	private ItemNode myFront; 
	


	
	public ItemLinkedList()
	{
		myFront = new ItemNode();  
		
	
		
	}
	
	public void clear()
	{
		myFront = null; 
	}
	
	public boolean addItem(Item product)
	{	boolean flag = false; 
		ItemNode addItem = new ItemNode ();
		addItem.data = product; 
	 
	 if (myFront.data == null)
	 {
		 myFront.next = addItem; 
		 flag = true; 
		 
	 }
	 
	 else {
		 ItemNode addItem2 = new ItemNode(); 
		 ItemNode current = new ItemNode(); 
		 ItemNode before = new ItemNode(); 
		  
		 
		 addItem2.data = product; 
		 before = current = myFront; 
		 
		 while (current.next != null)
		 {
			
			 current = current.next;
			 
			 
		 }
		 current.data = product; 
		
		 addItem.next = before.next; 
		 
		 before.next = addItem;  
		 
		 before = current; 
		
	 }
	 
	 return flag; 
	}
	
	public void printList()
	{
		ItemNode current = new ItemNode(); 
		current = myFront; 
		while (current != null)
	{
			System.out.println(current.data.toString()); 
			current = current.next;
	}
	}

class ItemNode
{
	public Item data; 
	public ItemNode next; 
	
	public ItemNode()
	{
		data = null;

	}
	
}
