public class DoubleSummaryStatisticsDemo {
    public static void main(String[] args)
    {

        DoubleSummaryStatistics doubleSummaryStatistics
            = new DoubleSummaryStatistics();

        List<Double> list = new LinkedList<>();
        list.add(95.7);
        list.add(234.6767);
        list.add(243.5);
        list.add(50.0);
        list.add(45.6);

        list.add(0.0);
        list.add(45664.7);

        Iterator<Double> iterator = list.listIterator();
        while (iterator.hasNext()) {

            // Add the doubles to the
            // DoubleSummaryStatistics object
            doubleSummaryStatistics
                .accept(iterator.next());
        }

        System.out.println(doubleSummaryStatistics
                               .toString());

        System.out.println("The maximum of values is "
                           + doubleSummaryStatistics
                                 .getMax());
    }
}

Output:

DoubleSummaryStatistics{count=10, sum=104682.953700, min=0.000000, average=10468.295370, max=45664.700000}
The maximum of values is 45664.7
