java 根据身份证号码获取出生日期、性别、年龄

 

1.情景展示

　　如何根据身份证号，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！

/**
 * 通过身份证号码获取出生日期、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;
}

　　根据身份证号提取出生日期

// 出生日期
String birthday = "";
// 身份证号不为空
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);
}

写在最后
