Getting index of first and last occurance of any element in the LinkedList

 

import java.util.LinkedList;

public class LinkedListIndexOfEle {

public static void main(String[] args) {

LinkedList<String> ll = new LinkedList<>();

//addding element to linkedlist ll

ll.add("Ishu");

ll.add("Nishu");

ll.add("Naina");

ll.add("Nishu");

ll.add("Shiksha");

//will give index of first occurance of Nishu

System.out.println(ll.indexOf("Nishu"));

//will give index of last occurance of Nishu

System.out.println(ll.lastIndexOf("Nishu"));

}

}
