LinkedTransferQueue iterator() method in Java

Last Updated : 14 Sep, 2018

The iterator() method of java.util.concurrent.LinkedTransferQueue is an in-built function in Java which is used to return an iterator over the elements in this queue in proper sequence. Syntax:

LinkedTransferQueue.iterator()

Return Value: The function returns an iterator over the elements in this queue in proper sequence. Below programs illustrate the LinkedTransferQueue.iterator() method: Program 1:

Java

// Java Program Demonstrate iterator()
// method of LinkedTransferQueue */

import java.util.Iterator;
import java.util.concurrent.LinkedTransferQueue;

class LinkedTransferQueueIteratorExample1 {
    public static void main(String[] args)
    {

        // Initializing the queue
        LinkedTransferQueue<String>
            queue = new LinkedTransferQueue<String>();

        // Adding elements to this queue
        queue.add("Gfg");
        queue.add("is");
        queue.add("fun!!");

        // Returns an iterator over the elements
        Iterator<String> iterator = queue.iterator();

        // Printing the elements of the queue
        while (iterator.hasNext())
            System.out.print(iterator.next() + " ");
    }
}

Output:

Gfg is fun!!

Program 2:

Java

// Java Program Demonstrate iterator()
// method of LinkedTransferQueue */

import java.util.Iterator;
import java.util.concurrent.LinkedTransferQueue;

class LinkedTransferQueueIteratorExample2 {
    public static void main(String[] args)
    {

        // Initializing the queue
        LinkedTransferQueue<Integer>
            queue = new LinkedTransferQueue<Integer>();

        // Adding elements to this queue
        queue.add(10);
        queue.add(15);
        queue.add(20);
        queue.add(25);

        // Returns an iterator over the elements
        Iterator<Integer> iterator = queue.iterator();

        // Printing the elements of the queue
        System.out.print("The queue contains ");
        while (iterator.hasNext())
            System.out.print(iterator.next() + " ");
    }
}

Output:

The queue contains 10 15 20 25
