Question

我的出生日期为06-03-2014（dd-mm-yyyy）格式。现在我想检查特定员工的年龄是否等于或超过18岁，与今天的日期相比。我怎么能在java.Please帮助

中这样做

Answer 1

你可以这样试试：

public static void main(String[] args) throws Exception {
    String dateString = "06-03-2014";
    Date date = new SimpleDateFormat("dd-MM-yyyy").parse(dateString);
    Calendar calendar = GregorianCalendar.getInstance();
    calendar.set(Calendar.YEAR, calendar.get(Calendar.YEAR) - 18);
    System.out.printf("Date %s is older than 18? %s", dateString, calendar.getTime().after(date));
}

Answer 2

你可以试试这个

DateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy");
Date date = new Date();
System.out.println("Current Date : "+dateFormat.format(date));
String dateInString = "24-03-2014";
Date date1 = dateFormat.parse(dateInString);
System.out.println(dateFormat.format(date1));
long diff = Math.abs(date.getTime() - date1.getTime());
long diffDays = diff / (24 * 60 * 60 * 1000);
System.out.println("Difference"+diffDays);
if(diffDays > 18){
    System.out.println("The employee above 18..");
}else{
    System.out.println("The employee below 18..");
}

java中的日期验证，用于检查年龄大于或等于18岁
