Remarks

A state object for collecting statistics such as count, min, max, sum, and average.

This class is designed to work with (though does not require) java.util.stream streams. For example, you can compute summary statistics on a stream of longs with:

{@code
            LongSummaryStatistics stats = longStream.collect(LongSummaryStatistics::new,
                                                             LongSummaryStatistics::accept,
                                                             LongSummaryStatistics::combine);
            }

LongSummaryStatistics can be used as a java.util.stream.Stream#collect(Collector) reduction target for a java.util.stream.Stream stream. For example:

{@code
            LongSummaryStatistics stats = people.stream()
                                                .collect(Collectors.summarizingLong(Person::getAge));
            }

This computes, in a single pass, the count of people, as well as the minimum, maximum, sum, and average of their ages.
