        while (ptr != null)
        {
            System.out.print(ptr.data + " ");
            ptr = ptr.next;
        }
    }
 
    // Reverses a given linked list by changing its `.next` fields and
    // its head.
    public static Node reverse(Node head)
    {
        Node previous = null;
        Node current = head;
 
        // traverse the list
        while (current != null)
        {
            // tricky: note the next node
            Node next = current.next;
 
            // fix the current node
            current.next = previous;   
            
            previous = current;
            current = next;
        }
 
        // fix the head to point to the new front
        return previous;
    }
 
    public static void main(String[] args)
    {
    	LinkedList list = new LinkedList();
    	
    	Scanner sc = new Scanner(System.in);
    	
        System.out.print("Input the number of nodes: ");
        int size = sc.nextInt();
    	
    	System.out.print("Please input data for node: ");
        int keys[] = new int[size];
        for(int i = 0; i < size; i++)
        {
        	keys[i] = sc.nextInt();
        	
        }
 
        Node head = null;
        for (int i = size - 1; i >= 0; i--) 
        {
            head = new Node(keys[i], head);
        }
 
        head = reverse(head);
        printList(head);
    }
}

What I have tried:

I think im not using the linked list
and I want to save a user input into the linked list
like if he inputs 3 nodes
then he will input a number to
node 1 = 5
node 2 = 6
node 3 = 7

and the output will be a reverse which i already done in my code

I just want it to print out like this

Input the number of nodes : 3

Input data for node 1 : 5
Input data for node 2 : 6
Input data for node 3 : 7

Data entered in the list are : 5 6 7

The list in reverse are : 7 6 5
