The remove() method of LinkedBlockingDeque removes the head of the Deque container. The method throws a NoSuchElementException if the Deque container is empty.
Syntax:
public E remove()
Parameters: This method does not accepts any parameter.
Returns: This method does not returns anything.
Exception: The function throws a NoSuchElementException if the Deque is empty.
Below programs illustrate remove() method of LinkedBlockingDeque:
Program 1:
// Java Program Demonstrate remove()// 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 front element        LBD.remove();        System.out.println("Linked Blocking Deque: " + LBD);    }} |
Output:
Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793] Linked Blocking Deque: [35658786, 5278367, 74381793]
Program 2:
// Java Program Demonstrate remove()// 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>(6);          // 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.remove();    }} |
Output:
Exception in thread "main" java.util.NoSuchElementException
