The java.util.concurrent.LinkedTransferQueue.put() method is an in-built function in Java which is used to insert an element in this queue. It waits till the space becomes available if queue is full.
Syntax:
LinkedTransferQueue.put(E e)
Parameters: The function accepts a single parameter e i.e. the element to be inserted.
Return Value: The function does not return anything.
Exception: The function shows NullPointerException when the specified element is Null.
Below programs illustrate the LinkedTransferQueue.put() method:
Program 1: Inserting Integers in the queue.
/* Java Program Demonstrate put()method of LinkedTransferQueue */  import java.util.concurrent.*;  class LinkedTransferQueuePutExample1 {    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.put(i);          // Printing the elements of the queue        System.out.println("The elements in the queue are:");        for (Integer i : queue)            System.out.print(i + " ");    }} |
Output:
The elements in the queue are: 10 11 12 13 14 15
Program 2: Adding String in the queue.
/* Java Program Demonstrate put()method of LinkedTransferQueue */  import java.util.concurrent.*;  class LinkedTransferQueuePutExample2 {    public static void main(String[] args)    {        // Initializing the queue        LinkedTransferQueue<String> queue =                      new LinkedTransferQueue<String>();          // Adding elements to this queue        queue.put("alex");        queue.put("bob");        queue.put("chuck");        queue.put("drake");        queue.put("erick");          // Printing the elements of the queue        System.out.println("The elements in the queue are:");        for (String i : queue)            System.out.print(i + " ");    }} |
Output:
The elements in the queue are: alex bob chuck drake erick
