Método BlockingDeque takeLast() en Java con ejemplos

El método takeLast() de BlockingDeque devuelve y elimina la cola del contenedor Deque. El método lanza una InterruptedException si se interrumpe mientras espera.

Sintaxis:  

public E takeLast()

Devoluciones: este método devuelve la cola (último elemento) del contenedor Deque. 

Excepción : la función lanza una InterruptedException si se interrumpe mientras espera.

Nota : El método takeLast() de BlockingDeque se ha heredado de la clase LinkedBlockingDeque en Java.

Los siguientes programas ilustran el método takeLast() de BlockingDeque:

Programa 1:  

// Java Program to demonstrate takeLast()
// method of BlockingDeque
 
import java.util.concurrent.LinkedBlockingDeque;
import java.util.concurrent.BlockingDeque;
import java.util.*;
 
public class GFG {
    public static void main(String[] args)
        throws InterruptedException
    {
 
        // create object of BlockingDeque
        BlockingDeque<Integer> BD
            = new LinkedBlockingDeque<Integer>();
 
        // Add numbers to end of BlockingDeque
        BD.add(7855642);
        BD.add(35658786);
        BD.add(5278367);
        BD.add(74381793);
 
        // print Deque
        System.out.println("Blocking Deque: " + BD);
 
        // removes the last element and prints it
        System.out.println("Head of Blocking Deque: "
                           + BD.takeLast());
 
        // prints the Deque
        System.out.println("Blocking Deque: " + BD);
    }
}

Blocking Deque: [7855642, 35658786, 5278367, 74381793]
Head of Blocking Deque: 74381793
Blocking Deque: [7855642, 35658786, 5278367]

Programa 2: 

// Java Program to demonstrate takeLast()
// method of BlockingDeque
 
import java.util.concurrent.LinkedBlockingDeque;
import java.util.concurrent.BlockingDeque;
import java.util.*;
 
public class GFG {
    public static void main(String[] args)
        throws InterruptedException
    {
 
        // create object of BlockingDeque
        BlockingDeque<Integer> BD
            = new LinkedBlockingDeque<Integer>();
 
        // Add numbers to end of BlockingDeque
        BD.add(7855642);
        BD.add(35658786);
        BD.add(5278367);
        BD.add(74381793);
 
        // print Deque
        System.out.println("Blocking Deque: " + BD);
 
        BD.clear();
 
        // throws error as the list is empty and it
        // is interrupted while waiting
        System.out.println("Head of Blocking Deque: "
                           + BD.takeLast());
    }
}

Errores de tiempo de ejecución: 

Max real time limit exceeded due to either by heavy load on server or by using sleep function
