I've met the condition of the qustion ( I think ) , but it's last condition is failed ...

Here is my code, maybe you can have a look~ import java.io.*; import java.util.Scanner; /* 偶数和奇数 */ public class Solution { public static int even; public static int odd; public static void main(String[] args) throws IOException { //在此编写你的代码 Scanner scanner = new Scanner(System.in); int a = scanner.nextInt(); even = 0; odd = 0; int b = String.valueOf(a).length(); for (int i = 0; i<b;i++){ if((a%10)%2==0){ even++; a=a/10; }else if((a%10)%2!=0){ odd++; a=a/10; } } System.out.println("偶数："+even+" 奇数："+odd); } }

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); String s = reader.readLine(); Integer l = s.length(); for(Integer i=0; i<l; i++){ Integer t = Integer.parseInt(s.substring(i,i+1)); if(t%2 == 0) { even++; }else{ odd++; } } System.out.println("偶数: " + even + " 奇数: " + odd);

package zh.codegym.task.task06.task0606; import java.io.*; /* 偶数和奇数 */ public class Solution { public static int even; public static int odd; public static void main(String[] args) throws IOException { //在此编写你的代码 BufferedReader reader=new BufferedReader(new InputStreamReader(System.in)); String A=reader.readLine(); //int a=Integer.parseInt(A); char[] ch=A.toCharArray(); for(int i=0;i<ch.length;i++) { // System.out.println(ch[i]); int a=ch[i]; if(a%2==0) { even++; } else { odd++; } } System.out.println("偶数: " + even +" 奇数: "+odd); } }

package zh.codegym.task.task06.task0606; import java.io.*; /* 偶数和奇数 */ public class Solution { public static int even; public static int odd; public static void main(String[] args) throws IOException { BufferedReader buffer = new BufferedReader(new InputStreamReader(System.in)); String s = buffer.readLine(); int n=Integer.parseInt(s); while(n>0) { if((n%10)%2==0) even++; else odd++; n/=10; } System.out.println("偶数: " + even +" 奇数: "+odd); } }

if you intput 0 ,this is 偶数should be1 but， 偶数 =0. in you code .
