Java：不能获得等于零的数字零

Question

我正在创建一个程序，将确定和打印数字奇数，偶数和零在一个整数从键盘。我尝试了几种不同的方法，每种方法都得到了相同的结果。我无法让java将0识别为0，而只能识别为偶数。例1005将给出2赔率和2平。

public static void main(String[] args) {
    int odd = 0;
    int even = 0;
    int zero = 0;
    int input;
Scanner scan = new Scanner (System.in); 

System.out.println("Input an integer please: ");
input = scan.nextInt();

System.out.println("Your number is: " + input);

String x = Integer.toString(input);

for (input = 0; input < x.length(); input++){
    char a = x.charAt(input);        
  System.out.println(a);

  Character.getNumericValue(a);

  if (a==0){
    System.out.println ("+1 Zero");
    zero++;
}
else if (a%2 == 0 && a>1){
    System.out.println("+1 Even");
    even++;
}
else {
    System.out.println("+1 Odd");
    odd++;
}

}
System.out.println("There are " + odd + " odd numbers!");
System.out.println("There are " + even + " even numbers!");
System.out.println("There are " + zero + " zero numbers!");
}

尚未将character.getNumericValue(a)赋值为int值。

  char a = x.charAt(input);        
  System.out.println(a);

 int y= Character.getNumericValue(a);

  if (y==0){
    System.out.println ("+1 Zero");
    zero++;
}
else if (y%2 == 0 && y>1){
    System.out.println("+1 Even");
    even++;
}
else {
    System.out.println("+1 Odd");
    odd++;
}
