ArrayBlockingQueue iterator() method in Java

Java 8Object Oriented ProgrammingProgramming

The iterator() method of the ArrayBlockingQueue class returns an iterator over the elements in this queue in proper sequence.

The syntax is as follows.

public Iterator<E> iterator()

To work with ArrayBlockingQueue class, you need to import the following package.

import java.util.concurrent.ArrayBlockingQueue;

The following is an example to implement iterator() method of Java ArrayBlockingQueue class.

Example

 Live Demo

import java.util.ArrayList;
import java.util.Iterator;
import java.util.concurrent.ArrayBlockingQueue;
public class Demo {
   public static void main(String[] args) throws InterruptedException {
      ArrayBlockingQueue<Integer> q = new ArrayBlockingQueue<Integer>(10);
      q.add(120);
      q.add(10);
      q.add(400);
      q.add(450);
      q.add(500);
      q.add(550);
      q.add(700);
      System.out.println("ArrayBlockingQueue = " + q);
      Iterator i = q.iterator();
      System.out.println("Iterating over the elements...");
      while (i.hasNext()) {
         System.out.println(i.next());
      }
   }
}

Output

ArrayBlockingQueue = [120, 10, 400, 450, 500, 550, 700]
Iterating over the elements...
120
10
400
450
500
550
700
