java - How to extract joda DateTime belonging to specific time range? -
suppose have collection
of datetimes
, how can filter datetime
objects have time between 10h00m , 12h30m?
for example:
new datetime(2013,1,1,10,0)
- right,
new datetime(2013,1,1,16,0)
- not.
parameters month, year, day not significant. ideas?
you can take advantage of joda's localtime
class here :
localtime lowerbound = new localtime(10, 0); localtime upperbound = new localtime(12, 30); list<datetime> filtered = new arraylist<>(); (datetime datetime : originals) { localtime localtime = new localtime(datetime); if (lowerbound.isbefore(localtime) && upperbound.isafter(localtime)) { filtered.add(datetime); } }
you may need tweak inclusive or exclusive, localtime
comparable
, , on top of that, has friendly compare methods readability.
