Challenge

Given the above Node class, what will the following code print?

public class Main { 
    public static void main(String[] args) {
        Node a = new Node(1);
        Node b = new Node(2);
        Node c = new Node(3);
        a.next = b;
        b.next = c;
        System.out.println(a.next.next.data);
    }
}
