Insert a Node at the Tail of a Linked List

    Why must you declare a "Node node = head"? Initially I had:

    if(head == null)
    {
        head = new Node();
        head.data = data;
    }
    else{
        while(head.next != null) head = head.next;
        head.next = new Node();
        head.next.data = data;
    }
    return head;

    But this method doesn't work. May you explain why? Thank you!
