Java:查找数组中的最大值 [英] Java: Finding the highest value in an array

问题描述

出于某种原因，当我尝试仅打印一个值(即 11.3)时，此代码打印了数组中最高值的三个值.有人可以向我解释为什么这样做吗?

For some reason this code is printing three values for the highest value in the array when I'm trying to print just one (which is 11.3). Can someone please explain to me why it is doing this?

谢谢.

import java.util.Scanner;

public class Slide24
{
    public static void main (String [] args)
    {
        Scanner in = new Scanner(System.in);

        double[] decMax = {-2.8, -8.8, 2.3, 7.9, 4.1, -1.4, 11.3, 10.4,
            8.9, 8.1, 5.8, 5.9, 7.8, 4.9, 5.7, -0.9, -0.4, 7.3, 8.3, 6.5, 9.2,
            3.5, 3, 1.1, 6.5, 5.1, -1.2, -5.1, 2, 5.2, 2.1};

        double total = 0, avgMax = 0;

        for (int counter = 0; counter < decMax.length; counter++)
        {
         total += decMax[counter];
        }

        avgMax = total / decMax.length;

        System.out.printf("%s %2.2f\n", "The average maximum temperature for December was: ", avgMax);

        //finds the highest value
        double max = decMax[0];

        for (int counter = 1; counter < decMax.length; counter++)
        {
         if (decMax[counter] > max)
         {
          max = decMax[counter];
          System.out.println("The highest maximum for the December is: " + max);
         }

        }        
    }
}

推荐答案

每当它发现一个高于当前最大值的数字时，它就会打印出一个数字(在您的情况下恰好发生了 3 次.)将打印移到外面for 循环，你应该很好.

It's printing out a number every time it finds one that is higher than the current max (which happens to occur three times in your case.) Move the print outside of the for loop and you should be good.

for (int counter = 1; counter < decMax.length; counter++)
{
     if (decMax[counter] > max)
     {
           max = decMax[counter];
     }
}

System.out.println("The highest maximum for the December is: " + max);
