public class DoubleSummaryStatisticsDemo {
    public static void main(String[] args)
    {
  
        DoubleSummaryStatistics doubleSummaryStatistics
            = new DoubleSummaryStatistics();
  
        List 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(45664.0);
        list.add(7007.777);
        list.add(5677.0);
        list.add(0.0);
        list.add(45664.7);
  
        Iterator iterator = list.listIterator();
        while (iterator.hasNext()) {
  
            // Add the doubles to the
            // DoubleSummaryStatistics object
            doubleSummaryStatistics
                .accept(iterator.next());
        }
  
        double value = 34.45;
        System.out.println("Inserting " + value
                           + " using accept() ");
  
        doubleSummaryStatistics
            .accept(value);
  
        System.out.println(doubleSummaryStatistics
                               .toString());
    }
}

输出：

Inserting 34.45 using accept()
DoubleSummaryStatistics{count=11, sum=104717.403700, min=0.000000, average=9519.763973, max=45664.700000}
