编写java应用程序，程序运行后，根据屏幕提示输入一个数字字符串，回车后统计有多少个偶数数字和奇数数字

import java.util.Scanner;

public class T14{

public static void main(String args[]){

System.out.println("请输入一串数字：");

Scanner in=new Scanner(System.in);

String a = in.next();

int odd = 0;

int even = 0;

for(int k = 0;k < a.length();k ++){

int i = (int)(a.charAt(k) - '0');

if(i % 2 == 0) {

even ++;

}else{

odd ++;

}

}

System.out.println("偶数：" + even);

System.out.println("奇数：" + odd);

}

}
