The isEmpty() method of java.util.concurrent.LinkedTransferQueue is an in-built function in Java which checks if this queue is empty or not.
Syntax:
LinkedTransferQueue.isEmpty()
Return Value: The function returns a boolean value. It returns true if the LinkedTransferQueue is empty and returns false otherwise.
Below programs illustrate the LinkedTransferQueue.isEmpty() method:
Program 1: In this program the LinkedTransferQueue is non-empty.
// Java Program Demonstrate isEmpty()// method of LinkedTransferQueue  import java.util.concurrent.*;  class LinkedTransferQueueIsEmptyExample1 {    public static void main(String[] args)    {          // Initializing the queue        LinkedTransferQueue<Integer>            queue = new LinkedTransferQueue<Integer>();          // Adding elements to this queue        for (int i = 10; i <= 15; i++)            queue.add(i);          // Checks if this queue is empty or not        if (queue.isEmpty())            System.out.println("The queue is empty.");        else            System.out.println("The queue is non-empty.");    }} |
Output:
The queue is non-empty.
Program 2:In this program the LinkedTransferQueue is empty.
// Java Program Demonstrate isEmpty()// method of LinkedTransferQueue */  import java.util.concurrent.*;  class LinkedTransferQueueIsEmptyExample2 {    public static void main(String[] args)    {          // Initializing the queue        LinkedTransferQueue<Integer>            queue = new LinkedTransferQueue<Integer>();          // Checks if this queue is empty or not        if (queue.isEmpty())            System.out.println("The queue is empty.");        else            System.out.println("The queue is non-empty.");    }} |
Output:
The queue is empty.
