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:
Java
Java
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:
Program 2:
Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793] Is Linked Blocking Deque empty: false
// 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
