1.情景展示

  如何根据SFZ号,计算出出生日期、性别、年龄?

2.解决方案

  从网上找的别人的,因为并没有实际用到,所以并未对其优化!

/**
 * 通过SFZ号码获取出生日期、性别、年龄
 * @param certificateNo
 * @return 返回的出生日期格式:1990-01-01 性别格式:F-女,M-男
 */
public static Map<String, String> getBirAgeSex(String certificateNo) {
    String birthday = "";
    String age = "";
    String sexCode = "";
 
    int year = Calendar.getInstance().get(Calendar.YEAR);
    char[] number = certificateNo.toCharArray();
    boolean flag = true;
    if (number.length == 15) {
        for (int x = 0; x < number.length; x++) {
            if (!flag)
                return new HashMap<String, String>();
            flag = Character.isDigit(number[x]);
        }
    } else if (number.length == 18) {
        for (int x = 0; x < number.length - 1; x++) {
            if (!flag)
                return new HashMap<String, String>();
            flag = Character.isDigit(number[x]);
        }
    }
    if (flag && certificateNo.length() == 15) {
        birthday = "19" + certificateNo.substring(6, 8) + "-" + certificateNo.substring(8, 10) + "-"
                + certificateNo.substring(10, 12);
        sexCode = Integer.parseInt(certificateNo.substring(certificateNo.length() - 3, certificateNo.length()))
                % 2 == 0 ? "F" : "M";
        age = (year - Integer.parseInt("19" + certificateNo.substring(6, 8))) + "";
    } else if (flag && certificateNo.length() == 18) {
        birthday = certificateNo.substring(6, 10) + "-" + certificateNo.substring(10, 12) + "-"
                + certificateNo.substring(12, 14);
        sexCode = Integer.parseInt(certificateNo.substring(certificateNo.length() - 4, certificateNo.length() - 1))
                % 2 == 0 ? "F" : "M";
        age = (year - Integer.parseInt(certificateNo.substring(6, 10))) + "";
    }
    Map<String, String> map = new HashMap<String, String>();
    map.put("birthday", birthday);
    map.put("age", age);
    map.put("sexCode", sexCode);
    return map;
}

  根据SFZ号提取出生日期

// 出生日期
String birthday = "";
// SFZ号不为空
if (sfzh.length() == 15) {
    birthday = "19" + sfzh.substring(6, 8) + "-" + sfzh.substring(8, 10) + "-" + sfzh.substring(10, 12);
} else if (sfzh.length() == 18) {
    birthday = sfzh.substring(6, 10) + "-" + sfzh.substring(10, 12) + "-" + sfzh.substring(12, 14);
}
