      Description

        A DESCRIPTION OF THE PROBLEM :
        Java Doc for Collectors.averagingInt states the following:
        ***************
        Returns:
        a Collector that produces the sum of a derived property
        ***************
        But it returns "arithmetic mean of an integer-valued function applied to the input elements"
        The same issue for averagingLong and averagingDouble

        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        Returns:
        a Collector that produces the arithmetic mean of an integer-valued function applied to the input elements
        ACTUAL -
        Returns:
        a Collector that produces the sum of a derived property
