    PriorityQueue<Integer> prq = new PriorityQueue<Integer>();

    // insert values in the queue
    prq.add(1);/*from   w ww  . j  a v  a  2s .  co m*/
    prq.add(2);
    prq.add(3);
    prq.add(6);
    prq.add(5);

    System.out.println(prq);

    // create comparator
    Comparator comp = prq.comparator();

    System.out.println("Comparator value is: " + comp);
}
