Linked List - nodes

Question

Hi,
In a lecture a couple of weeks ago, we began the topic of reference-based lists. I copied the attached
code off the board. I'm now trying to utilize the code by creating a public class Node. However, the constructors don't seem to make much sense. I was too busy writing down the information to pay much attention at the time. My book doesn't seem to address this...
1) in the first constructor: item = null; I'm declaring item initially as an integer, but the constructor is trying to attach a null to item. I think the intent is to create a node that initially has both info and link as nulls.
2) in the third constructor: link = Node; Is this possible? I'm not what this will do.
And finally, the second and third constructors are using the same name and parameter, so there is a conflict. I don't know how to resolve this.
Thanks in advance for any help...

public class Node {
          public int info;
          public Node link;
          public Node(){
               info = null;
               link = null;
          public Node (int data){
               info = data;
               link = null;
          public Node (int data){
               info = data;
               link = Node;

Answer 1

public class Node {
    public int info;
    public Node link;
    public Node(){
        // default constructor does nothing.
        // Therefore info and link will get default values.
        // For Objects this will be null
    public Node (int data){
        info = data;
        // don't initialise link. See above
    public Node (int data, Node node){
        // I think you missed the second parameter
        info = data;
        link = node;
}
