    Default where to put the nodes into the array?

    hi guys
    im implementing a basic singly linked list structure (Java class) it should allow the addition and deletion of a single (element in the linked list) at a specified position i. we can assume that each element is int.

    there is a code (I have couple of similar but this is better than at hers so far)

    3)
    public class Node{

    public int data;
    Node next;

    public Node getNextNode(Node n){
    return n;
    }

    public Node(int data){
    this.setData(data);
    }

    public Node(int data,Node next){
    this.setData(data);
    this.next=next;
    }

    public int getData() {

    return data;
    }

    public void setData(int data) {

    this.data = data;
    }
    this is to create the node, but struggling with where to put the nodes into the array?
    any advice
    thx

    You need to add some methods if you physically want to keep track of all the Nodes. First of all, you need a LinkedList which accepts Nodes' so you can keep track of every single node and a variable to keep track of the index of that certain node.
    LinkedList<Node> allNodes = new LinkedList<Node>();
    int index;

    Then, inside your constructor, you want to add a Node to the list of nodes.
    allNodes.add(this);
    index = allNodes.size()-1;

    Then, if you want to keep track of that certain index, you can make a method that returns the index.
    public int getIndex(){
    return index;
    }

    And that will return the index which holds all of that data.

    Honestly, I think it is the same problem. Same type of problem, and same user who's posting it.

    is it adding an array list?

    If you'd write a full sentence it would help those trying to help you.

    I'll take your suggestion. This thread is getting to be a waste of time.
