求字符串中大小写字母个数及其他符号个数！

    public static void main(String[] args) {
        Scanner scanner=new Scanner(System.in);
        char[] chars=new char[5];
        for (int i = 0; i < chars.length; i++) {
            System.out.println("请输入一个字符：");
            chars[i]= scanner.nextLine().charAt(0);
        }
        String s=String.valueOf(chars);
        System.out.println(s);
        int d=0,x=0,others=0;
        for (int i = 0; i < chars.length; i++) {
            if (chars[i]<='Z'&&chars[i]>='A'){
                d++;
            }else if (chars[i]<='z'&&chars[i]>='a'){
                x++;
            }else{
                others++;
            }
        }
        System.out.println("大写字母有"+d+"个。");
        System.out.println("小写字母有"+x+"个。");
        System.out.println("其他有"+others+"个。");
    }
