Added Reverse Linked List in java

class Node {
    int data;
    Node next;

    public Node(int data) {
        this.data = data;
        this.next = null;
    }
}

class LinkedList {
    Node head;

    public Node reverseLinkedList(Node head) {
        Node prev = null;
        Node current = head;

        while (current != null) {
            Node nextNode = current.next;
            current.next = prev;
            prev = current;
            current = nextNode;
        }

        return prev;  // New head of the reversed list
    }

    public void printLinkedList(Node head) {
        Node current = head;

        while (current != null) {
            System.out.print(current.data + " -> ");
            current = current.next;
        }
        System.out.print("null\n");
    }

    public static void main(String[] args) {
        LinkedList list = new LinkedList();
        list.head = new Node(1);
        list.head.next = new Node(2);
        list.head.next.next = new Node(3);
        list.head.next.next.next = new Node(4);
        list.head.next.next.next.next = new Node(5);

        System.out.println("Original linked list:");
