// Java Program to find an element in a Linked List
 
// Importing the Linked List class
import java.util.LinkedList;
 
class SearchInALinkedList {
    public static void main(String[] args)
    {
        // Initializing the Linked List
        LinkedList<Integer> ll = new LinkedList<>();
 
        // Adding elements to the Linked List
        ll.add(1);
        ll.add(2);
        ll.add(3);
        ll.add(4);
        ll.add(5);
        ll.add(6);
        ll.add(7);
 
        // Element to be searched
        int element = 4;
 
        // Initializing the answer to the index -1
        int ans = -1;
 
        // Traversing through the Linked List
        for (int i = 0; i < ll.size(); i++) {
 
            // Eztracting each element in
            // the Linked List
            int llElement = ll.get(i);
 
            // Checking if the extracted element is equal to
            // the element to be searched
