在数组中查找 max 和 min 的索引

Question

This is my code. I am using the bluej IDE.

    public class practice
    {
public int[] minMax(int[] num) {  
int smallest = num[0];
int largest = num[0];
int countsmall = 0;
int countlarge = 0;
for (int i = 0; i <= num.length - 1; i++){
    if (num[i] < smallest) smallest = num[i];
    if (num[i] > largest) largest = num[i];
}
for (int i = 0; i <= num.length - 1; i++){
    if (num[i] != smallest) countsmall++;
    if (num[i] != largest) countlarge++;
}
int array[] = {countsmall,countlarge};
return array;
}
}

I am trying to find the minimum and maximum value in an array which I successfully did. After that,I am trying to find its index. I created a variable count, and then went through the array. If that item in the array does not equal the minimum or maximum value, count+= count. However, for some reason its not working. The code compiles but returns the wrong value. Keep in mind I am not allowed to use java libraries. Any help would be much appreciated, thanks.

If you want also indexes of biggest and smallest, why dont you do it in one loop? eg:

public class practice
{
    public int[] minMax(int[] num) {  
      int smallest = num[0];
      int largest = num[0];
      int countsmall = 0;
      int countlarge = 0;
      for (int i = 0; i < num.length; i++){
        if (num[i] < smallest) {
            smallest = num[i];
            countsmall=i;
        }
        if (num[i] > largest) {
            largest = num[i];
            countlarge=i;
        }
      }
    
      int array[] = {countsmall,countlarge};
      return array;
    }
}
