Replace element with a new value in LinkedList

In the previous post, we have seen how to iterate over a list in reverse order. In this post, we will learn how to replace element with a new value in LinkedList.

We use a method ‘Set’ which accepts arguments as index and element value which will be replaced.

Syntax:

public E set(int index, E element)

Example:

import java.util.LinkedList;

public class LinkedListEx {

	public static void main(String[] args) {
		LinkedList<String> fruits = new LinkedList<String>();
		fruits.add("Orange");
		fruits.add("Mango");
		fruits.add("Apple");
		fruits.add("Grapes");
		fruits.add("Banana");
	
		System.out.println("List before replacement : "+fruits);
		
		fruits.set(0, "Papaya");
		System.out.println("List after replacement : "+fruits);
	}
}

Output:

List before replacement :[Orange, Mango, Apple, Grapes, Banana]
List after replacement :[Papaya, Mango, Apple, Grapes, Banana]
