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 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 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
