ArrayDeque Class removeLast() method

  • removeLast() method is available in java.lang package.
  • removeLast() method is used to return the last element but with removing the element from this deque.
  • removeLast() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • removeLast() method may throw an exception at the time of returning and removing an element from this deque.
    NoSuchElementException: This exception may throw when this deque is "blank".


    public T removeLast();


  • It does not accept any parameter.

Return value:

The return type of this method is T, it removes the last element with returning the element of this deque.


// Java program to demonstrate the example 
// of T removeLast() method of ArrayDeque 

import java.util.*;

public class RemoveLastOfArrayDeque {
    public static void main(String[] args) {
        // Creating an ArrayDeque with initial capacity of
        // storing elements
        Deque < String > d_queue = new ArrayDeque < String > (10);

        // By using add() method to add elements
        // in ArrayDeque

        // Display Deque Elements
        System.out.println("d_queue before removeLast(): ");
        System.out.println("ArrayDeque Elements = " + d_queue);


        // By using removeLast() method to remove
        // the last element of the ArrayDeque
        String ele = d_queue.removeLast();

        // Display Deque Elements
        System.out.println("d_queue after removeLast(): ");
        System.out.println("ArrayDeque Elements = " + d_queue);


d_queue before removeLast(): 
ArrayDeque Elements = [C, C++, Java, Php, DotNet]

d_queue after removeLast(): 
ArrayDeque Elements = [C, C++, Java, Php]
