Quick Question about linked lists

Question

If I have a linked list can i save it to a file directly with the Serializable interface or would I have to iterate through each element and write each element to the file?

Answer 1

yeah, it seems as though I can
However, I am having a problem reading it back. I guess I don't know how to initialize the values in the list, as it doens't recognize anything until I add an item to it and it adds this item to the front, then any other items after that it will add to the back, when i want this first addition to be in the back as well.
when I initialize the class i call
list.add(loadList());
loadList()
public MyList loadList() {
           try {
             FileInputStream fis = new FileInputStream("data.dat");
             ObjectInputStream in = new ObjectInputStream(fis);
             list = (MyList)in.readObject();
             in.close();
             return list;
           catch (Exception e) {
               System.out.println(e);
          return list;
       }list.add()
public void add(int index, Object o)
          if (index == 0) addFirst(o);
          else if (index >= size) addLast(o);
          else {
               Node current = first;
               for (int i = 1; i < index; i++)
                    current.prev = current;
                    current = current.next;
               Node temp = current.next;
               current.next = new Node(o);
               current.prev = current;
               (current.next).next = temp;
               size++;
     }any ideas?
