public static void main(String[] args) {
	PriorityQueue obQueue=new PriorityQueue();
	obQueue.add(1);
	obQueue.add(2);
	obQueue.add(3);
	obQueue.add(4);
	obQueue.add(5);
	Iterator obIt=obQueue.iterator();
	System.out.println("Element of queue");
	while (obIt.hasNext()) {
		System.out.print(obIt.next());
	}
	Object[] elementOf=obQueue.toArray();
	System.out.println("\nElement of array");
	for (int i = 0; i < elementOf.length; i++) {
		System.out.print(elementOf[i]);
	}
   }
}
