The java.util.concurrent.LinkedTransferQueue.size() method is an in-built function in Java which gives the total count of the elements present in the queue.
Syntax:
LinkedTransferQueue.size()
Parameters: The function does not accept any parameter.
Return Value: The function returns the number of elements in the queue.
Below programs illustrate the LinkedTransferQueue.size() method:
Program 1:
// Java Program Demonstrate size()// method of LinkedTransferQueue   import java.util.concurrent.LinkedTransferQueue;  class LinkedTransferQueueSizeExample1 {    public static void main(String[] args)    {        // Initializing the queue        LinkedTransferQueue<Integer> queue =                      new LinkedTransferQueue<Integer>();          // Adding elements to this queue        for (int i = 1; i <= 10; i++)            queue.add(i);          // Printing the size of the queue        System.out.println("Number of elements in the queue = "                                                 + queue.size());        // Printing the elements        System.out.println("Queue : " + queue);    }} |
Output:
Number of elements in the queue = 10 Queue : [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
Program 2:
// Java Program Demonstrate size()// method of LinkedTransferQueue   import java.util.concurrent.LinkedTransferQueue;  class LinkedTransferQueueSizeExample2 {    public static void main(String[] args)    {        // Initializing the queue        LinkedTransferQueue<String> queue =                   new LinkedTransferQueue<String>();          // Adding elements to this queue        queue.add("A");        queue.add("B");        queue.add("C");        queue.add("D");        queue.add("E");          // Printing the size of the queue        System.out.println("Number of elements in the queue = "                                                 + queue.size());        // Printing the elements        System.out.println("Queue : " + queue);    }} |
Output:
Number of elements in the queue = 5 Queue : [A, B, C, D, E]
