Java中的 DoubleSummaryStatistics getMax() 方法及示例

Java中 DoubleSummaryStatistics 类的getMax()方法用于获取此 DoubleSummaryStatistics 中的最大记录数。

句法：

public double getMax()

参数：此方法不接受任何值作为参数。

返回值：此方法返回此 DoubleSummaryStatistics 中记录的最大值。

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

输出：

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