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; }</string,></string,></string,></string,></string,>
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 ); }
