Create linked list using for loop Java

class LinkedList { // create an object of Node class // represent the head of the linked list Node head; // static inner class static class Node { int value; // connect each node to next node Node next; Node[int d] { value = d; next = null; } } // check if loop is present public boolean checkLoop[] { // create two references at start of LinkedList Node first = head; Node second = head; while[first != null && first.next !=null] { // move first reference by 2 nodes first = first.next.next; // move second reference by 1 node second = second.next; // if two references meet // then there is a loop if[first == second] { return true; } } return false; } public static void main[String[] args] { // create an object of LinkedList LinkedList linkedList = new LinkedList[]; // assign values to each linked list node linkedList.head = new Node[1]; Node second = new Node[2]; Node third = new Node[3]; Node fourth = new Node[4]; // connect each node of linked list to next node linkedList.head.next = second; second.next = third; third.next = fourth; // make loop in LinkedList fourth.next = second; // printing node-value System.out.print["LinkedList: "]; int i = 1; while [i
