    In a Java Queue, poll() and remove() methods can be used for

    removing the head object of Queue. The main difference arises in

    the case when Queue is empty().

    If Queue is empty then poll() method returns null value. If Queue is

    empty then remove() method throws NoSuchElementException.

    In a Java Queue, peek() method retrieves the head of Queue but it

    does not remove it. If queue is empty then peek() method returns

    null value.
