Java – Remove first and last element from LinkedList example

Last Updated: September 11, 2022 by Chaitanya Singh | Filed Under: java

In this tutorial we will learn how to remove First and Last elements from LinkedList. In the few last posts we shared following tutorials:

1) Removing elements from a specific index
2) Removing specific element from LinkedList

Example

We have used removeFirst() method to remove first and removeLast() method to remove last element from LinkedList. Method definition and description are as follows:

1) public E removeFirst(): Removes and returns the first element from this list.
2) public E removeLast(): Removes and returns the last element from this list.

Complete Code:

import java.util.LinkedList;
public class RemoveExample {
 
 public static void main(String[] args) {
 
    // Create a LinkedList
    LinkedList<String> linkedlist = new LinkedList<String>();
 
    // Add elements to LinkedList
    linkedlist.add("Item1");
    linkedlist.add("Item2");
    linkedlist.add("Item3");
    linkedlist.add("Item4");
    linkedlist.add("Item5");
 
    // Displaying Elements before remove
    System.out.println("LinkedList Elements are:");
    for(String str: linkedlist){
       System.out.println(str);
    }
 
    // Removing First element
    Object firstElement = linkedlist.removeFirst();
    System.out.println("\nElement removed: "+ firstElement);
 
    // Removing last Element
    Object lastElement = linkedlist.removeLast();
    System.out.println("Element removed: "+ lastElement);
 
    // LinkedList elements after remove
    System.out.println("\nList Elements after Remove:");
    for(String str2: linkedlist){
       System.out.println(str2);
    }
 }
}

Output:

LinkedList Elements are:
Item1
Item2
Item3
Item4
Item5

Element removed: Item1
Element removed: Item5

List Elements after Remove:
Item2
Item3
Item4
