原文:https://www . geesforgeks . org/double summarystatistics-accept-method-in-Java-with-examples/

Java 中 DoubleSummaryStatistics 类的 accept() 方法用于将给定值接受到这个汇总信息中。

语法:

public void accept(double value)

参数:此方法接受值作为要记录到此双摘要统计中的参数。

返回值:这个方法不返回任何东西。

程序:

// 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());
        }

        double value = 34.45;
        System.out.println("Inserting " + value
                           + " using accept() ");

        doubleSummaryStatistics
            .accept(value);

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

Output:

使用 accept() 插入 34.45 double summarystatistics { count = 11,sum=104717.403700,min=0.000000,average=9519.763973,max=45664.700000}
