How to replace element in LinkedList

 We can replace any specific index element by other element using set(int index,element) method.


import java.util.LinkedList;

public class ReplaceElement {

    public static void main(String[] args) {
       
        LinkedList<String> linkedList = new LinkedList<String>();
       
        linkedList.add("Mumbai");
        linkedList.add("Delhi");
        linkedList.add("Noida");
        linkedList.add("Gao");
        linkedList.add("Patna");
        //print linkedlist
        System.out.println("Before Replace Element Linklist is = "+linkedList);
       
        /*
         * Replaces the element at the specified position in
         * this list with the specified element.
         */
       
        linkedList.set(2,"chandigarh");
       
        System.out.println("After Replace Element Linklist is = "+linkedList);
       
    }   
   
}

Output:

Before Replace Element Linklist is = [Mumbai, Delhi, Noida, Gao, Patna]

After Replace Element Linklist is = [Mumbai, Delhi, chandigarh, Gao, Patna]
