    public class HelloWorld {
        public static void main(String[] args) {
            //转换为字符串
            String cmd = "32,30,32,31,32,33,34,35,36,37,38,00,00,00";
            String a = "10";//长度(16进制)
            int length = Integer.parseInt(a, 16);//转换的长度
            char temp;
            StringBuilder builder = new StringBuilder();
            for (int i = 0; i < length; i++) {
                if (cmd.split(",")[i].equals("00")) break;    //已"00"结束
                temp = (char) Integer.parseInt(cmd.split(",")[i], 16);
                builder.append(temp);
            }
            String number = builder.toString();
            System.out.println(number);
        }
    }
