The isEmpty() method of LinkedBlockingDeque in Java is used to check whether this LinkedBlockingDeque is empty or not. It returns an boolean value stating the same.
Syntax:
public boolean isEmpty()
Parameters: This method does not accepts parameter.
Returns: The method returns an boolean value which states that this instance of the LinkedBlockingDeque is empty or not.
Below examples illustrates the LinkedBlockingDeque.isEmpty() method:
Program 1:
// Java Program Demonstrate isEmpty()// method of LinkedBlockingDeque  import java.util.concurrent.LinkedBlockingDeque;import java.util.*;  public class GFG {    public static void main(String[] args)        throws IllegalStateException    {          // 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);          System.out.println("Linked Blocking Deque: " + LBD);          // using isEmpty() function        System.out.println("Is Linked Blocking Deque empty: "                           + LBD.isEmpty());    }} |
Output:
Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793] Is Linked Blocking Deque empty: false
Program 2:
// Java Program Demonstrate isEmpty()// method of LinkedBlockingDeque// when the list contains characters  import java.util.concurrent.LinkedBlockingDeque;import java.util.*;  public class GFG {    public static void main(String[] args)        throws IllegalStateException    {          // create object of LinkedBlockingDeque        LinkedBlockingDeque<String> LBD            = new LinkedBlockingDeque<String>();          System.out.println("Linked Blocking Deque: " + LBD);          // using isEmpty() function        System.out.println("Is Linked Blocking Deque empty: "                           + LBD.isEmpty());    }} |
Output:
Linked Blocking Deque: [] Is Linked Blocking Deque empty: true
