LinkedBlockingDeque isEmpty() method in Java with Example

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
