Thanks Jerry,
you are right, it's pretty much more a numerical stuff than a date
manipulation.
Thanks to Anfy who helped me clear that, I did a method (not very
optimized for now) that will get the warranty to a combination of
year,month,week which will do the trick for now.
Thanks for you input, I'll mark it to make sure I won't forget when
I'll get back to optimize this method.

If you've stored the warranty information as an integer number of
weeks in your database, and you're willing to accept 1 month = 4
weeks (exactly), then you've got a simple numeric problem rather
than a date problem.
I would approach it in something like the following way:
public String warrantyUnit(int warrantyWeeks) {
if ((warrantyWeeks / 52) * 52 == warrantyWeeks) {
return "years";
if ((warrantyWeeks / 4) * 4 == warrantyWeeks) {
return "months";
return weeks;
}
public int warrantyTime(int warrantyWeeks, String warrantyUnit) {
if ("years".isEqual(warrantyUnit))
return (warrantyWeeks / 52);
if ("months".isEqual(warrantyUnit))
return (warrantyWeeks / 4);
return warrantyWeeks;
}
Under Objective C, I would have defined warranty as a structure:
struct warranty {
String unit;
int period;
}
and done the whole job in a single method that returned said
structure, but we're no longer in that environment and making
warranty a Java class seemed a little heavy handed.
Regards,
Jerry

Hi,
I'm not sure the subject is correct, but here's my problem:
I've got warranty validity information stored as weeks in the
database. I'd like to display them in either week(s), month or year
(s), but not like "3.5 month", I'd like the number to always be an
integer (not rounded), so a 6 weeks warranty will be displayed "6
weeks" and a 4 weeks warranty will be dispayed "1 month".
Does anyone has a suggestion for this? I tried to dig into
different date APIs (like the apache common and the java one), but
I don't think it's the way to go...
Thanks
Xavier
