ArrayBlockingQueue iterator() method in Java
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
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
