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:
import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;
public class GFG {
public static void main(String[] args)
throws IllegalStateException
{
LinkedBlockingDeque<Integer> LBD
= new LinkedBlockingDeque<Integer>();
LBD.add( 7855642 );
LBD.add( 35658786 );
LBD.add( 5278367 );
LBD.add( 74381793 );
System.out.println( "Linked Blocking Deque: " + LBD);
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:
import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;
public class GFG {
public static void main(String[] args)
throws IllegalStateException
{
LinkedBlockingDeque<String> LBD
= new LinkedBlockingDeque<String>();
System.out.println( "Linked Blocking Deque: " + LBD);
System.out.println( "Is Linked Blocking Deque empty: "
+ LBD.isEmpty());
}
}
|
Output:
Linked Blocking Deque: []
Is Linked Blocking Deque empty: true
