12/28/2016, 6:44 PM@jo looks like foo.dropLast(1) would do it👍 1 - j
jo
12/28/2016, 6:44 PMWould that mutate foo? - d
dpk
12/28/2016, 6:44 PMno, just returns a new array - d

12/28/2016, 6:46 PMCopy codefun someFun(days: Int): Boolean { return days == 0 } - d
davicdsalves
12/28/2016, 6:46 PMwhy I can't compare Int to 0? - a

12/28/2016, 6:47 PMSergey, weird, because my Json example earlier would compile. - j

12/28/2016, 6:47 PMval is a key word - d
davicdsalves
12/28/2016, 6:47 PMsorry, val is just a bad example name - e
enleur
12/28/2016, 6:47 PM@davicdsalves
is reservedval - d
davicdsalves
12/28/2016, 6:48 PMsorry about that, just replaced it. idea is complaining that I'm comparing an Int to 0 - d
davicdsalves
12/28/2016, 6:48 PMoperator '==' cannot be applied to 'Long' and 'Int' - d
davicdsalves
12/28/2016, 6:48 PMbut that's acceptable in Java. weird so what should I use? compare? - j
jan.rabe
12/28/2016, 6:49 PMworks for me just fine - d
davicdsalves
12/28/2016, 6:49 PMhmmm - e
enleur
12/28/2016, 6:49 PMit works. can you show exact error message? - d
davicdsalves
12/28/2016, 6:50 PMseems that the problem's because days, is (firstDay % lastDay) - d
davicdsalves
12/28/2016, 6:51 PMand firstDay is long. - d
damian
12/28/2016, 6:51 PM@adam-mcneilly Types from java whose nullability can't be determined are "platform types", like
or `JsonElement!`: https://kotlinlang.org/docs/reference/java-interop.html#null-safety-and-platform-typesString!👍 1🙈 1😮 1 - d
davicdsalves
12/28/2016, 6:51 PMso return firstDay % lastDay == 0 doesnt work. - d
davicdsalves
12/28/2016, 6:52 PMbecause firstDay is long, lastDay is int - j
jo
12/28/2016, 6:52 PM@dpk Thanks! - a
adam-mcneilly
12/28/2016, 6:53 PM@damian21214 Exactly the explanation I was looking for, thanks! - j
jo
12/28/2016, 6:55 PM@davicdsalves (firstDay as Int % lastDay) ? - d
davicdsalves
12/28/2016, 6:56 PMThis cast can never succeed - j
jo
12/28/2016, 6:56 PM(firstDay % lastDay as Long)? - d
davicdsalves
12/28/2016, 6:56 PMthats the message. - d
davicdsalves
12/28/2016, 6:56 PMthis worked == 0L - j
jo
12/28/2016, 6:56 PMAh. - d
davicdsalves
