The getSum() method of DoubleSummaryStatistics class in Java is used to get the sum of records in this DoubleSummaryStatistics.
Syntax:
public double getSum()
Parameter: This method do not accept any value as parameter.
Return Value: This method returns the sum of the records in this DoubleSummaryStatistics.
Program:
// Java program to demonstrate// the above method  import java.util.*;  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(45664.0);        list.add(7007.777);        list.add(5677.0);        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 sum of values is "                           + doubleSummaryStatistics                                 .getSum());    }} |
Output:
DoubleSummaryStatistics{count=10, sum=104682.953700, min=0.000000, average=10468.295370, max=45664.700000}
The sum of values is 104682.9537
