Calendar currentDate = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
String dateNow = sdf.format(currentDate.getTime());
Date today = new Date(dateNow);
Date finalDay = null;
finalDay = (Date) sdf.parse("MM/dd/yyyy");
int numberOfDays=(int)((finalDay.getTime()-today.getTime())/(3600*24*1000));

you can use Date.compareTo()method.
您可以使用Date.compareTo()方法。
DateComparedateTime(String date1)
{
System.out.println(new SimpleDateFormat("yyyy/MM/dd HH:mm:ss").format(date1).compareTo(new Date()))
}

this might help you...follow it carefully..
这可能会帮助你......仔细遵循它......
Calendar c = Calendar.getInstance();
int seconds = c.get(Calendar.SECOND);
System.out.println("calender time in millies" + c.getTimeInMillis());
System.out.println("calender time in millies" + c.getTime());
long diffInSec = TimeUnit.MILLISECONDS.toSeconds(c.getTimeInMillis());
System.out.println("time in seconds :: " + diffInSec);
