Question

public class LinkedList{
private class Node{
private Object data;
private Node next;
public Node(Object data){
this.data = data;
next = null
}
}
private Node head;
public LinkedList(){
head = null;
}
public void add(Object data){
Node n = new Node(data);
n.next = head;
head = n;
}
Can anyone explain linked list? from above code, what would n.next = head exactly do? It seems to me that n is pointing to head and the next line is making head pointing to n. So they are pointing at each other?

Answer 1

this is how I see it but n.next should point to null not head correct? would setting = head make n.next point to null?
