public class LinkedList {
    private Node head; // head of the linked list

    // Node class representing the nodes of the linked list
    private static class Node {
        int data; // data stored in the node
        Node next; // reference to the next node

        // Constructor to create a new node with the given data
        Node(int data) {
            this.data = data;
            next = null;
        }
    }

    // Method to insert a new node at the end of the linked list
    public void insert(int data) {
        Node newNode = new Node(data); // Create a new node with the given data

        if (head == null) {
            head = newNode; // If the list is empty, make the new node as the head
        } else {
            Node current = head;
            while (current.next != null) {
                current = current.next; // Traverse to the last node
            }
            current.next = newNode; // Insert the new node at the end
        }
    }

    // Method to print the linked list
    public void printList() {
        Node current = head;
        System.out.print("LinkedList: ");
        while (current != null) {

            current = current.next; // Move to the next node
        }
