The java.util.concurrent.ConcurrentLinkedDeque.isEmpty() is an in-built function in Java which checks whether the deque contains elements or not.
Syntax:
public boolean isEmpty()
Parameters: The function does not accepts any parameter.
Return: This method returns a boolean value stating whether this deque is empty or not.
Below programs illustrate the ConcurrentLinkedDeque.isEmpty() method:
Example: 1
// Java Program Demonstrate// isEmpty() method of ConcurrentLinkedDeque import java.util.concurrent.*; class ConcurrentLinkedDequeDemo { public static void main(String[] args) { ConcurrentLinkedDeque<String> cld = new ConcurrentLinkedDeque<String>(); // Displaying the existing LinkedDeque System.out.println("ConcurrentLinkedDeque: " + cld); // Check if the queue is empty // using isEmpty() method System.out.println("Is deque empty: " + cld.isEmpty()); }} |
Output:
ConcurrentLinkedDeque: [] Is deque empty: true
Example: 2
// Java Program Demonstrate// isEmpty() method of ConcurrentLinkedDeque import java.util.concurrent.*; class ConcurrentLinkedDequeDemo { public static void main(String[] args) { ConcurrentLinkedDeque<String> cld = new ConcurrentLinkedDeque<String>(); cld.add("GFG"); cld.add("Gfg"); cld.add("Lazyroar"); cld.add("Geeks"); // Displaying the existing LinkedDeque System.out.println("ConcurrentLinkedDeque: " + cld); // Check if the queue is empty // using isEmpty() method System.out.println("Is deque empty: " + cld.isEmpty()); }} |
Output:
ConcurrentLinkedDeque: [GFG, Gfg, Lazyroar, Geeks] Is deque empty: false
