Removelast() java - Java LinkedList removeLast() Method with Examples

Removelast() java: In the previous article, we have discussed about Java LinkedList removeIf() Method with Examples

In this article we are going to see the use of Java LinkedList removeLast() method along with suitable examples.

Java LinkedList removeLast() Method with Examples

This java.util.LinkedList.removeLast() method is used to remove any single element from the last/tail of the LinkedList. It returns the last element which got removed.

Syntax:

LinkedListName.removeLast()

Where,

LinkedListName refers to the name of your LinkedList.

Let’s see removeLast() method with suitable examples.

Example with String Type LinkedList
Example with Integer Type LinkedList

Example-1: Java LinkedList removeLast() Method – Example with String Type LinkedList

Approach:

Create a new LinkedList of type String.
Add String elements into the LinkedList using the add() method.
Display the LinkedList elements.
Then remove the last element from the LinkedList using removeLast() method.
Print the new LinkedList.

Program:

import java.util.*;
public class Main
{
    public static void main(String[] args)
    {
        // Create a LinkedList of string datatype
        LinkedList<String> l = new LinkedList<String>();
        // Adding some elements to the LinkedList
        l.add("Hello");
        l.add("this");
        l.add("is");
        l.add("an");
        l.add("example of removeLast() method");
        // Prints the LinkedList elements
        System.out.println("The elements of LinkedList are: "+l);
        // removing the last element from the LinkedList
        l.removeLast();
        // Prints the new LinkedList elements
        System.out.println("The new elements of LinkedList are: "+l);
    }
}

Output:

The elements of LinkedList are: [Hello, this, is, an, example of removeLast() method]
The new elements of LinkedList are: [Hello, this, is, an]

Example-2: Java LinkedList removeLast() Method – Example with Integer Type LinkedList

Approach:

Create a new LinkedList of type Integer.
Add integer elements into the LinkedList using the add() method.
Display the LinkedList elements.
Then remove the last element from the LinkedList using removeLast() method.
Print the new LinkedList.

Program:

import java.util.*;
public class Main
{
    public static void main(String[] args)
    {
        // Create a LinkedList of Integer datatype
        LinkedList<Integer> l = new LinkedList<Integer>();
        // Adding some elements to the LinkedList
        l.add(2);
        l.add(4);
        l.add(6);
        l.add(8);
        l.add(10);
        // Prints the LinkedList elements
        System.out.println("The elements of LinkedList are: "+l);
        // removing the last element from the LinkedList
        l.removeLast();
        // Prints the new LinkedList elements
        System.out.println("The new elements of LinkedList are: "+l);
    }
}

Output:

The elements of LinkedList are: [2, 4, 6, 8, 10]
The new elements of LinkedList are: [2, 4, 6, 8]
