Java – Add element at specific index in LinkedList example

In this tutorial we will learn how to add a new element at specific index in LinkedList. We will be using add(int index, Element E) method of LinkedList class to perform this operation.

More about this method from javadoc:
public void add(int index, E element): Inserts the specified element at the specified position in this list. Shifts the element currently at that position (if any) and any subsequent elements to the right (adds one to their indices).

Example

In this example we have a LinkedList of Strings and we are adding an element to its 5th position(4th index) using add() method. The complete code is as follows:

import java.util.LinkedList;
import java.util.Iterator;
public class AddElement {
 
 public static void main(String[] args) {
 
    // Create a LinkedList
    LinkedList<String> linkedlist = new LinkedList<String>();
 
    // Add elements to LinkedList
    linkedlist.add("Delhi");
    linkedlist.add("Agra");
    linkedlist.add("Mysore");
    linkedlist.add("Chennai");
    linkedlist.add("Pune");
 
    // Adding new Element at 5th Position 
    linkedlist.add(4, "NEW ELEMENT");

    // Iterating the list in forward direction
    System.out.println("LinkedList elements After Addition:");
    Iterator it= linkedlist.iterator();
    while(it.hasNext()){
       System.out.println(it.next());
    }
 }
}

Output:

LinkedList elements After Addition:
Delhi
Agra
Mysore
Chennai
NEW ELEMENT
Pune
