写段Java代码通过身份证号码解析出年龄，性别，生日

以下是Java代码，可以通过身份证号码解析出年龄，性别和生日：

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;

public class IdCardParser {

    public static void main(String[] args) {
        String idCard = "110101199003077777";
        String birthday = getBirthday(idCard);
        String gender = getGender(idCard);
        int age = getAge(idCard);
        System.out.println("Birthday: " + birthday);
        System.out.println("Gender: " + gender);
        System.out.println("Age: " + age);
    }

    public static String getBirthday(String idCard) {
        String birthday = "";
        if (idCard.length() == 18) {
            birthday = idCard.substring(6, 14);
        } else if (idCard.length() == 15) {
            birthday = "19" + idCard.substring(6, 12);
        }
        SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
        try {
            Date date = sdf.parse(birthday);
            birthday = sdf.format(date);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return birthday;
    }

    public static String getGender(String idCard) {
        String gender = "";
        if (idCard.length() == 18) {
            gender = idCard.substring(16, 17);
        } else if (idCard.length() == 15) {
            gender = idCard.substring(14, 15);
        }
        int genderNum = Integer.parseInt(gender);
        if (genderNum % 2 == 0) {
            return "Female";
        } else {
            return "Male";
        }
    }

    public static int getAge(String idCard) {
        int age = 0;
        Calendar calendar = Calendar.getInstance();
        int currentYear = calendar.get(Calendar.YEAR);
        int birthYear = 0;
        if (idCard.length() == 18) {
            birthYear = Integer.parseInt(idCard.substring(6, 10));
        } else if (idCard.length() == 15) {
            birthYear = Integer.parseInt("19" + idCard.substring(6, 8));
        }
        age = currentYear - birthYear;
        return age;
    }
}

注意：这段代码只是一个简单的示例，实际应用中需要考虑更多的情况，比如身份证号码的合法性等。
