1.把出生日期字符串转换为日期格式. public static Date parse(String strDate) throws ParseException { SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd"); return sdf.parse(strDate); } 2.计算年龄 public static int getAge(Date birthDay) throws Exception { Calenda

根据生日计算年龄可以通过Calendar实现.最简单可以考虑get(Calendar.DAY_OF_YEAR)来简单修正年龄,但是遇到生日在闰年的2月29之后,或者今年是闰年的2月29之后可能出现计算不准,误差一天.所以还是老实判断年月日好了. // 根据生日计算年龄,判断了年月日,比简单的年份上计算更精准 public static int getAge(Date birthDay) throws Exception {         Calendar cal = Calendar.getI

在Sqlserver中,可以根据存储的出生年月字段计算出该用户的当前年龄信息,主要使用到DateDiff函数来实现.DateDiff函数的格式为DATEDIFF(datepart,startdate,enddate),两个表达式中的参数datepart表示单位计量,startdate表示开始时间,enddate表示结束时间. datepart 参数可以是下列的值: datepart 缩写 年 yy, yyyy 季度 qq, q 月 mm, m 年中的日 dy, y 日 dd,d 周 wk, ww

朋友谈及身份证相关的信息,才了解到原来省份证号码中包含了年龄和性别. 这样在数据库中,就不必单独留字段存放它们了(不过,要根据具体情况来,要是读取频率较高,还是单独列出为好),这样顺带解决了年龄变更的问题. 程序仅仅为了实现这个功能,里面还是需要数据验证的,用户输入的信息,毕竟在猿类看来,都是“非法的”.废话不多说了,贴上我写的程序,还请路过的大神斧正: using System; using System.Collections.Generic; using System.Linq; usin
