使用
String ID_18 = "321083197812162119";
String ID_15 = "150102880730303";

//是否有效
boolean valid = IdcardUtil.isValidCard(ID_18);

//转换
String convert15To18 = IdcardUtil.convert15To18(ID_15);
Assert.assertEquals(convert15To18, "150102198807303035");

//年龄
DateTime date = DateUtil.parse("2017-04-10");

int age = IdcardUtil.getAgeByIdCard(ID_18, date);
Assert.assertEquals(age, 38);

int age2 = IdcardUtil.getAgeByIdCard(ID_15, date);
Assert.assertEquals(age2, 28);

//生日
String birth = IdcardUtil.getBirthByIdCard(ID_18);
Assert.assertEquals(birth, "19781216");

String birth2 = IdcardUtil.getBirthByIdCard(ID_15);
Assert.assertEquals(birth2, "19880730");

//省份
