what is wrong with below code ? can any anyone help me ,thanks

still can not pass the text test, both of them can not pass .so sad package zh.codegym.task.task06.task0606; import java.io.*; public class Solution { public static int even = 0; public static int odd = 0; 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 n = reader.readLine(); for(int i=0;i<n.length();i++){ int temp = n.charAt(i)-'0'; if(temp % 2 == 0){ even += 1;} else{ odd +=1;} } System.out.print("偶数：" + even + " 奇数：" + odd); } }

I think the problem is going to be that negative numbers in your code produce the incorrect result. Try adding this to line 11 (right after the user input and before the loop):

n = n.replaceAll("[^0-9]", "");

This line will remove all chars that are not numbers, including the negative '-' qualifier.
