The ConcurrentLinkedDeque.removeLast() is an in-built function in Java which removes the last element in the deque. The function throws a NoSuchElementException if this deque is empty. Syntax:
Conn_Linked_Deque.removeLast()
Parameters: The function does not accepts any parameter. Return Values: The function returns the last element in the deque. Exception: The function throws a NoSuchElementException if this deque is empty. Below program illustrates the removeLast() method: Program 1: This program involves deque with Integer elements. Java
// Java Program Demonstrate removeLast() 
// method of ConcurrentLinkedDeque   

import java.util.concurrent.*;

class ConcurrentLinkedDequeDemo {
    public static void main(String[] args)
    {
        ConcurrentLinkedDeque<Integer> cld = 
                      new ConcurrentLinkedDeque<Integer>();

        cld.addFirst(12);
        cld.addFirst(70);
        cld.addFirst(1009);
        cld.addFirst(475);

        // Displaying the existing LinkedDeque
        System.out.println("Elements in"
                           + "the LinkedDeque: " + cld);

        // Display the last element
        System.out.println("Element removed : "
                           + cld.peekLast());

        // Remove the Last element
        cld.removeLast();

        // Displaying the elements
        System.out.println("Elements in"
                           + "the LinkedDeque: " + cld);
    }
}
Output:
Elements inthe LinkedDeque: [475, 1009, 70, 12]
Element removed : 12
Elements inthe LinkedDeque: [475, 1009, 70]
Program 2: This program involves deque with String elements. Java
// Java Program Demonstrate removeLast() 
// method of ConcurrentLinkedDeque   

import java.util.concurrent.*;

class ConcurrentLinkedDequeDemo {
    public static void main(String[] args)
    {
        ConcurrentLinkedDeque<String> cld = 
                           new ConcurrentLinkedDeque<String>();

        cld.addFirst("GFG");
        cld.addFirst("Gfg");
        cld.addFirst("GeeksforGeeks");
        cld.addFirst("Geeks");

        // Displaying the existing LinkedDeque
        System.out.println("Elements in"
                           + "the LinkedDeque: " + cld);

        // Display the last element
        System.out.println("Element removed : "
                           + cld.peekLast());

        // Remove the Last element
        cld.removeLast();

        // Displaying the elements
        System.out.println("Elements in"
                           + "the LinkedDeque: " + cld);
    }
}
Output:
Elements inthe LinkedDeque: [Geeks, GeeksforGeeks, Gfg, GFG]
Element removed : GFG
Elements inthe LinkedDeque: [Geeks, GeeksforGeeks, Gfg]
