Remove First and Last element from the LinkedList
In the previous post, we have seen how to add element at a specified index. In this post, we will see how to remove first and last element from the LinkedList.
We have methods like removeFirst() and removeLast() which are used to remove First and Last elements from the LinkedList.
Syntax:
public E removeFirst()
: This is used to remove the first element from the LinkedList.
public E removeLast()
: This is used to remove the last element from the LinkedList.
Example:
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"); fruits1.removeFirst(); System.out.println("Removed first element :"+ fruits1); //Remove Orange fruits1.removeLast(); System.out.println("Removed last element :"+ fruits1); //Remove Grapes } }
Output:
Removed first element :[Mango, Apple, Grapes]
Removed last element :[Mango, Apple]
