String patientDOB = driver.findElement(id("patient_profile_widget_form_birthday")).getAttribute("value");

有什么主意吗？：）

Answer 1

使用Java 8

public int calculateAge(
  LocalDate birthDate) {
    // validate inputs ...
    return Period.between(birthDate, LocalDate.now());
}

Answer 2

private static final DateFormat FORMATTER = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss z", Locale.US);
String patientDOB = driver.findElement(id("patient_profile_widget_form_birthday")).getAttribute("value");

Date dateOfBirth = getDateFromString(patientDOB);
public Date getDateFromString(final String patientDOB) {
    try {
        return FORMATTER.parse(param);
    } catch (ParseException e) {
        throw new Exception("ParseException occurred while parsing date ", e);
    }
}

public static int getAge(Date dateOfBirth) {
Calendar today = Calendar.getInstance();
Calendar birthDate = Calendar.getInstance();
birthDate.setTime(dateOfBirth);
if (birthDate.after(today)) {
    throw new IllegalArgumentException("You don't exist yet");
}
int todayYear = today.get(Calendar.YEAR);
int birthDateYear = birthDate.get(Calendar.YEAR);
int todayDayOfYear = today.get(Calendar.DAY_OF_YEAR);
int birthDateDayOfYear = birthDate.get(Calendar.DAY_OF_YEAR);
int todayMonth = today.get(Calendar.MONTH);
int birthDateMonth = birthDate.get(Calendar.MONTH);
int todayDayOfMonth = today.get(Calendar.DAY_OF_MONTH);
int birthDateDayOfMonth = birthDate.get(Calendar.DAY_OF_MONTH);
int age = todayYear - birthDateYear;

// If birth date is greater than todays date (after 2 days adjustment of leap year) then decrement age one year
if ((birthDateDayOfYear - todayDayOfYear > 3) || (birthDateMonth > todayMonth)){
    age--;

// If birth date and todays date are of same month and birth day of month is greater than todays day of month then decrement age
} else if ((birthDateMonth == todayMonth) && (birthDateDayOfMonth > todayDayOfMonth)){
    age--;
}
return age;

}

Answer 3

创建一个包装器方法，将字符串作为参数，

使用：

 String[] parts = string.split("/");

，然后选择列表的第三项。

然后您只需要使用：

int year = Calendar.getInstance().get(Calendar.YEAR);

得到你的一年。然后，您只需将年份字符串转换为int并将其减去
