getting and setting dates with Java

Question

First off thank you for taking the time to scroll through this.

I am basically a greenhorn when it comes to Java but I am working on a program that asks the user some basic info then sets a start date and then schedules service dates at bi weekly intervals between March and October from their start date.

For the start date variable, I simply set it up as:

STARTDATE = getDate();

to give the current date when the user signs up.

I have been sifting through my searches for days but I cannot figure out how to increment the service dates by 14 days to save my life.

I tried using SERVICEDATE = STARTDATE + (0, 14, 0); but I cant make sense of whats really happening here. Any ideas?

"...sifting through my searches..." what does that mean? – azurefrog May 29 '14 at 20:45 — azurefrog, May 29 '14 at 20:45
What is the **type** of `STARTDATE`? – PM 77-1 May 29 '14 at 20:49 — PM 77-1, May 29 '14 at 20:49

Use the common-lang library. It has a DateUtils class which can be used for this. Use it like this:

SERVICEDATE = DateUtils.addDays(STARTDATE, 14);

Thanks, that seems to work. Now how can I limit it so it wont accept dates between nov and feb? – NixondisNRVA May 29 '14 at 22:09
`Date yourdate = new Date(); Calendar calendar = new GregorianCalendar(); calendar.setTime(yourdate); int month = calendar.get(Calendar.MONTH); if(month >= Calendar.FEBRUARY && month <= Calendar.NOVEMBER){ }` – marcellsimon May 31 '14 at 08:44

Maybe have a look at this: Java getDate date-x days

They are subtracting days but I think it can be turned into adding days too.

I suggest you use Joda Library

Date STARTDATE = getDate();
DateTime stDate = new DateTime(STARTDATE);
//Date after 14 days
DateTime rsDate = stDate.plusDays(14);
