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(); }} |
