Question

How to count even and odd digits in an integer with Java

Answer 1

// An Automorphic number is a number whose square ends with the same digits 
// as the original number. E.g – 5 : 5 * 5 = 25 //ends with 5 

public class Main {
    public static int even = 0, odd = 0;

    public static void countEvenOdd(int n) {
        while (n > 0) {
            int reminder = n % 10;
            if (reminder % 2 == 0)
                even++;
            else
                odd++;
            n = n / 10;
        }
    }
    public static void main(String args[]) {
        int n = 1907834;
     
        countEvenOdd(n);
     
        System.out.println("Total even = " + even);
        System.out.println("Total odd = " + odd);
    }
}




/*
run:
 
Total even = 3
Total odd = 4
 
*/
