所以我在java中使用数组，我遇到了一个问题，我试图列出一个长度为100的数组中出现次数最少的数字的位置，范围为0-9 . 我正在使用第二个数组来计算出现次数，直到我的最后一段代码都可以解决。

import java.util.Random;

public class Program6
{
public static void main(String[] args) 
{
    int[] bigArray = new int[100];
    int[] count = new int[10];


    for (int i = 0; i < bigArray.length ;i++ )
        {
            bigArray[i] = (int)(Math.random() * 10);    
        }
    for (int i = 0; i < bigArray.length ;i++ )  
        {   
            System.out.println(bigArray[i] + " ");  
        }
    for(int i = 0; i < bigArray.length; i++)
        {
            count[bigArray[i]]++;
        }



    for (int i = 0, j = 0; i < count.length ;i++, j++)  
            System.out.println("count for " + j +" is: " + count[i] + " "); 

    int min = count[0];
    int indexOfMin = 0;

    for ( int i =1; i < count.length; i++)
        {   if (count[i] < min ) 
                {
                    min = count[i];
                    indexOfMin = i; 
                }
        }

    System.out.println("\nThe number " + indexOfMin + " only appears " + min  + " times in the array.");
    System.out.println("It appears in the large array at: ");

    \\this guy right here 
    for ( int i = 0 ; i < bigArray.length; i++)
        {   if (bigArray[i] == min ) 
                {
                    System.out.println("bigArray["+ i + "]");

                }
        }

}

}

它应该只列出阵列位置。但它返回的不仅仅是最低出现整数的位置，即使限定符使用变量min。

是什么赋予了？我错过了什么？

没有输入，返回的输出是

8 
 ..
4 
count for 0 is: 18 
count for 1 is: 6 
count for 2 is: 9 
count for 3 is: 9 
count for 4 is: 16 
count for 5 is: 4 
count for 6 is: 12 
count for 7 is: 8 
count for 8 is: 7 
count for 9 is: 11     

The number 5 only appears 4 times in the array.
It appears in the large array at: 
bigArray[3]
bigArray[6]
bigArray[10]
bigArray[23]
bigArray[25]
bigArray[39]
bigArray[44]
bigArray[48]
bigArray[49]
bigArray[50]
bigArray[51]
bigArray[57]
bigArray[58]
bigArray[67]
bigArray[84]
bigArray[99]

这是完美的，除了 bigArray[] 列表。当数组等于最少出现的数字时，它应该只显示索引的位置。

您正在与数字的计数进行比较。请改用该号码。更新

//this guy right here 
for ( int i = 0 ; i < bigArray.length; i++)
    {   if (bigArray[i] == min ) 
            {
                System.out.println("bigArray["+ i + "]");

            }
    }

indexOfMin用作_

`//this guy right here 
for ( int i = 0 ; i < bigArray.length; i++)
    {   if (bigArray[i] == indexOfMin) 
            {
                System.out.println("bigArray["+ i + "]");

            }
    }
