Conteos XOR de 0 y 1 en representación binaria

Dado un número, la tarea es encontrar XOR de conteo de 0s y conteo de 1s en representación binaria de un número dado. 
Ejemplos: 
 

Input  : 5
Output : 3
Binary representation : 101
Count of 0s = 1, 
Count of 1s = 2
1 XOR 2 = 3.

Input  : 7
Output : 3
Binary representation : 111
Count of 0s = 0
Count of 1s = 3
0 XOR 3 = 3.

C++

// C++ program to find XOR of counts 0s and 1s in
// binary representation of n.
#include<iostream>
using namespace std;
  
// Returns XOR of counts 0s and 1s in
// binary representation of n.
int countXOR(int n)
{
    int count0 = 0, count1 = 0;
    while (n)
    {
        //calculating count of zeros and ones
        (n % 2 == 0) ? count0++ :count1++;
        n /= 2;
    }
    return (count0 ^ count1);
}
  
// Driver Program
int main()
{
    int n = 31;
    cout << countXOR (n);
    return 0;
}

Java
