最小和最大的输入 [英] smallest and largest of the inputs

问题描述

我被分配编写一个程序，读取一系列整数输入并打印
-输入中最小和最大的
-以及偶数和奇数输入的数量

I was assigned to write a program that read a sequence of integer inputs and print -the smallest and largest of the inputs -and the number of even and odd inputs

我想出了第一部分，但我很难理解如何让程序显示最大和最小。到目前为止这是我的代码。如何让它显示最小的输入？

I figured out the first part but am stumped on how I can get my program to display the largest and the smallest. This is my code so far. How can I get it to display the smallest input aswell?

public static void main(String args[])
{
      Scanner a = new Scanner (System.in);
      System.out.println("Enter inputs (This program calculates the largest input):");

      double largest = a.nextDouble();
      while (a.hasNextDouble())
      { 
          double input = a.nextDouble();
          if (input > largest)
          {
              largest = input;
          }
      }


      System.out.println(largest);
}

推荐答案

最简单的解决方案是使用类似 Math.min 和 Math.max

The simplest solution would be use something like Math.min and Math.max

double largest = a.nextDouble();
double smallest = largest;
while (a.hasNextDouble()) {
    double input = a.nextDouble();
    largest = Math.max(largest, input);
    smallest = Math.min(smallest, input);
}
