    Default Nodes

    So I absolutely cannot figure out nodes. I have no clue what I am doing. I can't figure out how to do the add method. So far all I have is:


    public class List{
     
        Node head = null; //the start of the linked list
        private 
     
        public void add(Object next, int index){
            if(head == null){ //adding to an empty list (changes head)
                head = new Node(next, head);     //what about index?
            }else if( ){ //adding to a single element list (changes head)
     
            }else if(){ //adding to a populated list (n>=2)
                Node temp = head;
                while(temp.next != null){
                    temp = temp.next;
                }
                temp.next = new Node(next, index) //not correct.....
            }
     
        }
    }

    Where is the algorithm you are trying to write code to? or did you skip that part?
