LinkedTransferQueue take() method in Java

Last Updated : 14 Sep, 2018

The java.util.concurrent.LinkedTransferQueue.take() method is an in-built function in Java which retrieves and remove the first element of the queue. This method also waits (if necessary) until an element becomes available. Syntax:

  LinkedTransferQueue.take()

Parameters: The function does not accept any parameter. Return Value: The function returns the first element of the queue. Exceptions: The function throws InterruptedException if interrupted while waiting. Below programs illustrate the java.util.concurrent.LinkedTransferQueue.take() : Program 1:

Java

// Java Program Demonstrate take() // method of LinkedTransferQueue   import java.util.concurrent.LinkedTransferQueue;  class LinkedTransferQueueTakeExample1 {     public static void main(String[] args) throws Exception     {         // Initializing the queue         LinkedTransferQueue<String> queue =                          new LinkedTransferQueue<String>();          // Adding elements to this queue         queue.add("Alex");         queue.add("Bob");         queue.add("Chuck");         queue.add("Drake");         queue.add("Eric");          // Printing the elements         System.out.println("Elements are :");         for (String xyz : queue) {             // will take and remove the head of the queue             System.out.println(queue.take());         }          // Printing the size of the Queue         System.out.println("Queue Size: " + queue.size());     } }

Output:

  Elements are :  Alex  Bob  Chuck  Drake  Eric  Queue Size: 0

Program 2:

Java

// Java Program Demonstrate take() // method of LinkedTransferQueue   import java.util.concurrent.LinkedTransferQueue;  class LinkedTransferQueueTakeExample2 {     public static void main(String[] args) throws Exception     {         // Initializing the queue         LinkedTransferQueue<Integer> queue =                          new LinkedTransferQueue<Integer>();          // Adding elements to this queue         for (int i = 1; i <= 5; i++)             queue.add(i);          // Printing the elements         System.out.println("Elements are :");         for (Integer xyz : queue) {             // will take and remove the head of the queue             System.out.println(queue.take());         }         // Printing the size of the Queue         System.out.println("Queue Size: " + queue.size());     } }

Output:

  Elements are :  1  2  3  4  5  Queue Size: 0
