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 ints with:

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

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

{@code
            IntSummaryStatistics stats = people.stream()
                                               .collect(Collectors.summarizingInt(Person::getDependents));
            }

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