### Printing a Linked List in Java Given a standard linked list of integers (`int`), `L`, we want to write two methods to print the elements of `L` in order: 1. Using a loop. 2. Using recursion. We will start printing from `head.next`. #### Using a Loop Below is the Java code to print the elements of a linked list using a loop: ```java class Node { int data; Node next; Node(int d) { data = d; next = null; } } public class LinkedList { Node head; // head of the list /* Function to print linked list using loop starting from head.next */ void printListUsingLoop() { Node temp = head.next; // Start from the next node while (temp != null) { System.out.print(temp.data + " "); temp = temp.next; } } public static void main(String[] args) { LinkedList list = new LinkedList(); // Creating a simple linked list list.head = new Node(1); Node second = new Node(2); Node third = new Node(3); list.head.next = second; // Link first node with the second node second.next = third; // Link second node with the third node list.printListUsingLoop(); } } ``` #### Using Recursion Below is the Java code to print the elements of a linked list using recursion: ```java class Node { int data; Node next; Node(int d) { data = d; next = null; } } public class LinkedList { Node head; // head of the list /* Function to print linked list using recursion starting from head.next */ void printListUsingRecursion(Node node) { if (node == null) { return; // Base case: end of the list } System.out.print(node.data + " "); printListUsingRecursion(node.next); } public static void main(String[] args) { LinkedList list = new LinkedList(); // Creating a simple linked list list.head = new Node(1); Node second = new Node(2); Node third = new Node(3); list.head.next = second; //
