下面一段代碼給大家分享java根據(jù)身份證計算年齡的方法,具體代碼如下所示:

birthDate = idCard.substring(6,10)+"-"+idCard.substring(10,12)+"-"+idCard.substring(12,14) public static int getAgefromBirthTime(String birthTimeString){ // 先截取到字符串中的年、月、日 String strs[] = birthTimeString.trim().split("-"); int selectYear = Integer.parseInt(strs[0]); int selectMonth = Integer.parseInt(strs[1]); int selectDay = Integer.parseInt(strs[2]); // 得到當(dāng)前時間的年、月、日 Calendar cal = Calendar.getInstance(); int yearNow = cal.get(Calendar.YEAR); int monthNow = cal.get(Calendar.MONTH) + 1; int dayNow = cal.get(Calendar.DATE); // 用當(dāng)前年月日減去生日年月日 int yearMinus = yearNow - selectYear; int monthMinus = monthNow - selectMonth; int dayMinus = dayNow - selectDay; int age = yearMinus; if (yearMinus < 0) {// 選了未來的年份 age = 0; } else if (yearMinus == 0) {// 同年的,要么為1,要么為0 if (monthMinus < 0) {// 選了未來的月份 age = 0; } else if (monthMinus == 0) {// 同月份的 if (dayMinus < 0) {// 選了未來的日期 age = 0; } else if (dayMinus >= 0) { age = 1; } } else if (monthMinus > 0) { age = 1; } } else if (yearMinus > 0) { if (monthMinus < 0) {// 當(dāng)前月>生日月 } else if (monthMinus == 0) {// 同月份的,再根據(jù)日期計算年齡 if (dayMinus < 0) { } else if (dayMinus >= 0) { age = age + 1; } } else if (monthMinus > 0) { age = age + 1; } } return age; }
下面在看下java根據(jù)出生日期獲得年齡
public static int getAge(Date birthDay) throws Exception { Calendar cal = Calendar.getInstance(); if (cal.before(birthDay)) { throw new IllegalArgumentException( "The birthDay is before Now.It's unbelievable!"); } int yearNow = cal.get(Calendar.YEAR); int monthNow = cal.get(Calendar.MONTH); int dayOfMonthNow = cal.get(Calendar.DAY_OF_MONTH); cal.setTime(birthDay); int yearBirth = cal.get(Calendar.YEAR); int monthBirth = cal.get(Calendar.MONTH); int dayOfMonthBirth = cal.get(Calendar.DAY_OF_MONTH); int age = yearNow - yearBirth; if (monthNow <= monthBirth) { if (monthNow == monthBirth) { if (dayOfMonthNow < dayOfMonthBirth) age--; }else{ age--; } } System.out.println("age:"+age); return age; }
總結(jié)
以上所述是小編給大家介紹的JAVA 根據(jù)身份證計算年齡,希望對大家有所幫助,如果大家有任何疑問請給我留言,小編會及時回復(fù)大家的。在此也非常感謝大家對創(chuàng)新互聯(lián)網(wǎng)站的支持!
