Add Element at a specified index

In the previous post, we have seen how to add an element to a LinkedList.In this post, we will see how to add element at a specified index.

We will use method add(int index, Objects o) to add an element to LinkedList at a specified Index.

Syntax:

public void add(int index, Objects o)

index: It is an integer value and the position where the element will be added. Index starts from zero(0).

Objects o:  It is the element which needs to be added.

Example:

In the below example we have a LinkedList which contains fruits names. We will add a new fruit at index 2.

import java.util.LinkedList;

public class LinkedListEx {

	public static void main(String[] args) {
		LinkedList<String> fruits1 = new LinkedList<String>();
		fruits1.add("Orange");
		fruits1.add("Mango");
		fruits1.add("Apple");
		fruits1.add("Grapes");
		
		System.out.println("All fruits before adding index :"+ fruits1);
		
		fruits1.add(2, "Banana");
		System.out.println("All fruits after adding index :"+ fruits1);
	}
}

Output:

All fruits before adding index :[Orange, Mango, Apple, Grapes]
All fruits after adding index :[Orange, Mango, Banana, Apple, Grapes]
