You should be able to access if directly, or using static getter methods...

If this is your Queue class...

public class Queue {
    public static LinkedList myList = new LinkedList();

    public static ListedList getMyList(){
        return myList;
    }
}

Then you could access your list be either calling Queue.myList or Queue.getMyList() - both will do the same thing. The benefit of using a getter method would be that you can control access to the list, such as by making the method synchronized, preventing calls to the list being out of order.
