removeLast()

method of LinkedBlockingDeque:

Program 1: Java


 // Java Program to demonstrate removeLast()
// method of LinkedBlockingDeque

import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;

public class GFG {
    public static void main(String[] args)
        throws InterruptedException
    {

        // create object of LinkedBlockingDeque
        LinkedBlockingDeque<Integer> LBD
            = new LinkedBlockingDeque<Integer>();

        // Add numbers to end of LinkedBlockingDeque
        LBD.add(7855642);
        LBD.add(35658786);
        LBD.add(5278367);
        LBD.add(74381793);

        // print Dequeue
        System.out.println("Linked Blocking Deque: " + LBD);

        // removes the last element and prints it
        System.out.println("Linked Blocking Deque: " +      
                        LBD.removeLast());

        // prints the Deque
        System.out.println("Linked Blocking Deque: " + LBD);
    }
}

Output:

Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793]
Linked Blocking Deque: 74381793
Linked Blocking Deque: [7855642, 35658786, 5278367]

Program 2: Java


 // Java Program to demonstrate removeLast()
// method of LinkedBlockingDeque

import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;

public class GFG {
    public static void main(String[] args)
        throws NoSuchElementException
    {

        // create object of LinkedBlockingDeque
        LinkedBlockingDeque<Integer> LBD
            = new LinkedBlockingDeque<Integer>();

        // Add numbers to end of LinkedBlockingDeque
        LBD.add(7855642);
        LBD.add(35658786);
        LBD.add(5278367);
        LBD.add(74381793);

        // print Dequeue
        System.out.println("Linked Blocking Deque: " + LBD);

        // Deque is empty
        LBD.clear();

        // throws an exception
        LBD.removeLast();
    }
}

Output:

Exception in thread "main" java.util.NoSuchElementException
    at java.util.concurrent.LinkedBlockingDeque.removeLast(LinkedBlockingDeque.java:462)
    at GFG.main(GFG.java:29)
