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 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 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
