Remove First and Last Elements of Linkedlist in Java

In this post, we will learn how to remove the first and last element from LinkedList using the following APIs:

• removeFirst()
• removeLast()

Let's first create LinkedList with few fruits and then use remove methods to remove fruits from LinkedList.

LinkedList<String> fruitList = new LinkedList<>();

fruitList.add("Apple");
fruitList.add("banana");
fruitList.add("mango");
fruitList.add("Pinaple");

System.out.println("Initial LinkedList = " + fruitList);

removeFirst()

Remove the first element in the LinkedList. Throws NoSuchElementException if the LinkedList is empty.

String element = fruitList.removeFirst();   
System.out.println("Removed the first element " + element + " => " + fruitList);

removeLast()

Remove the last element in the LinkedList. Throws NoSuchElementException if the LinkedList is empty

element = fruitList.removeLast();    
System.out.println("Removed the last element " + element + " => " + fruitList);

Complete Example

package com.javaguides.collections.linkedlistexamples;

import java.util.LinkedList;

public class RemoveElementsFromLinkedListExample {
    public static void main(String[] args) {
        LinkedList < String > fruitList = new LinkedList < > ();

        fruitList.add("Apple");
        fruitList.add("banana");
        fruitList.add("mango");
        fruitList.add("Pinaple");

        System.out.println("Initial LinkedList = " + fruitList);

        // Remove the first element in the LinkedList
        String element = fruitList.removeFirst();
        System.out.println("Removed the first element " + element + " => " + fruitList);

        // Remove the last element in the LinkedList
        element = fruitList.removeLast();
        System.out.println("Removed the last element " + element + " => " + fruitList);
    }
}

Output

Initial LinkedList = [Apple, banana, mango, Pinaple]
Removed the first element Apple => [banana, mango, Pinaple]
Removed the last element Pinaple => [banana, mango]
