Java 中 DoubleSummaryStatistics 类的 getMin() 方法用来获取这个 DoubleSummaryStatistics 中最少的记录。
语法:

参数:此方法不接受任何值作为参数。
返回值:该方法返回该 DoubleSummaryStatistics 中记录的最小值。
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<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 minimum of values is "
+ doubleSummaryStatistics
.getMin());
}
}
Output:
double summary statistics { count = 10,sum=104682.953700,min=0.000000,average=10468.295370,max=45664.700000} 最小值为 0.0
