Java uses toCharArray to take each digit of the input string and print the number of odd and even numbers

import java.io.*;

/* Even and odd */

public class Solution {

    public static int even;
    public static int odd;

    public static void main(String[] args) throws IOException {
        // Write your code here
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        String num = reader.readLine();
        char[] c = num.toCharArray();
        for (int i = 0; i < c.length; i++) {
            switch (c[i] % 2) {
                case 0:
                    even++;
                    break;
                default:
                    odd++;
                    break;
            }
        }
        System.out.println("Even:" + even +  "Odd:"+ odd); }}Copy the code
