I have to find the difference in time between two different date objects in java and if that time exceeds 5 sec i have to invalidate the session.
Here's the scenario :
I have a jsp page which set the session every 5 sec
session.setAttribute( "sessionAccessedAt", new Date() ); I have a another jsp page which is accessed every 1 sec ,
Date date2 = new Date(); Now i have to compare in the another jsp that i have mentioned and invalidate the session,
Date date1 = (Date)session.getAttribute("sessionAccessedAt"); Date date2 = new Date(); Differnce = date2 - date1; Thereby if the difference exceeds 5 sec, invalidating the session.
324
String start = "12:00:00"; String end = "02:05:00"; SimpleDateFormat format = new SimpleDateFormat("HH:mm:ss"); Date date1 = format. parse(start); Date date2 = format. parse(end); long difference = date2. getTime() - date1.
Using JodaTime, you can get the difference between two dates in Java using the following code: Days d = Days. daysBetween(startDate, endDate). getDays();
minus(long amountTosubtract, TemporalUnit unit) minus() method of a LocalTime class used to returns a copy of this LocalTime with the specified amount of unit subtracted. If it is not possible to subtract the amount, because the unit is not supported or for some other reason, an exception is thrown.
long difference = date2.getTime() - date1.getTime(); // now you have your answer in milliseconds - //so divide by 1000 to get the time in seconds If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
