Iterating over a linked list in Java?

Iterating over a linked list in Java?

I have been diligently watching YouTube videos in an effort to understand
linked lists before my fall classes start and I am uncertain how to
proceed with iterating over the following linked list. The 'node' class is
from a series of videos (same author), but the 'main' method was written
by me. Am I approaching the design of a linked list in an illogical
fashion (assuming of course one does not wish to use the predefined
LinkedList class since the professor will expect each of us to write our
own implementation)?:
class Node
{
private String data;
private Node next;
public Node(String data, Node next)
{
this.data = data;
this.next = next;
}
public String getData()
{
return data;
}
public Node getNext()
{
return next;
}
public void setData(String d)
{
data = d;
}
public void setNext(Node n)
{
next = n;
}
public static String getThird(Node list)
{
return list.getNext().getNext().getData();
}
public static void insertSecond(Node list, String s)
{
Node temp = new Node(s, list.getNext());
list.setNext(temp);
}
public static int size(Node list)
{
int count = 0;
while (list != null)
{
count++;
list = list.getNext();
}
return count;
}
}
public class LL2
{
public static void main(String[] args)
{
Node n4 = new Node("Tom", null);
Node n3 = new Node("Caitlin", n4);
Node n2 = new Node("Bob", n3);
Node n1 = new Node("Janet", n2);
}
}
Thanks for the help,
Caitlin
