Hello. I am new to java and stuck at Linked List reverse problem and don't know how to solve it

Question

It's showing some kind to error at head "Cannot resolve symbol 'head' ".

import java.util.LinkedList;

public class reversellusingiteration {
    static Node head;

    static class Node{
        int data;
        Node next;
        Node(int d) {
            this.data = d;
            this.next = null;
        }
    }

    Node reverse(Node node){
        Node curr=node;
        Node prev=null;
        while(curr!=null){
            Node temp=curr.next;
            curr.next=prev;
            prev=curr;
            curr=temp;
        }
        return prev;
    }
    public static void main(String[] args) {
        LinkedList list=new LinkedList();
        list.head =new Node(90); //here is the problem
        list.head.next=new Node(78);
    }
}

Please someone help me with this

Answer 1

Your class reversellusingiteration has two problems. The static Node head; should not be static. And it is not named LinkedList. So you need to change

LinkedList list=new LinkedList();

to

reversellusingiteration list = new reversellusingiteration();
