Hi,
I'm stuck on a doubly linked list program. I need to find the length of a list, add a node at the beginning, and print the list. Each node stores an integer and a reference, and the list is doubly linked so there's a head as well as a tail. Some node methods are getNext, getPrevious, setNext, setPrevious...
I'm pretty sure I got some logical errors here...

Thank you for any help!

CODE
    public int lengthFinder(){
        int counter = 0;
        Node temp = head;
        while(temp!=null){
        temp = temp.getNext();
        counter++;
        }
    return counter;
    }

    public void addANodeAtBeginning(int newData){
        Node other = new Node(newData, head);
        head = other;
    }

    public void print() {
        Node temp = head;
        while(temp!=null){
        System.out.print(temp.getData() + " ");
        temp = temp.getNext();
        }
        System.out.println();
    }/
