12/21/2016, 4:48 PMI don't follow. In Java I can doString passed = isSuccess ? "Passed" : "Failed"; - r
Ruckus
12/21/2016, 4:49 PMYes, but you cannot doString passed = if (isSuccess) "Passed" else "Failed"; - a
adam-mcneilly
12/21/2016, 4:49 PMOhh. I can't do that if statement on one line in Java. - k
kenneth_ford
12/21/2016, 4:49 PMin kotlin that would turn into `val passed = if (isSuccess) “passed” else “failed" - r
Ruckus
12/21/2016, 4:49 PMYou can in Kotlin, so you don't need the ternary - a
adam-mcneilly
12/21/2016, 4:49 PMSo was it deemed that if/else was more readable than ternary? - a
adam-mcneilly
12/21/2016, 4:50 PMI'm going to miss this. 😞 I used it quite often haha - j
jw
12/21/2016, 4:50 PMit was deemed unnecessary - k
kenneth_ford
12/21/2016, 4:50 PMit’s the same thing though? and it’s hard to say that a colon and question mark is more readable than actual words - j
jw
12/21/2016, 4:50 PMwhy add syntactic complexity when the functionality already exists with the existing 'if' primitive👍 8 - k

12/21/2016, 4:51 PMotherwise, it will be groovy all over again - a
adam-mcneilly
12/21/2016, 4:51 PMThat's fair. I guess it's just a habit I have to break. I don't have any profound reason for it. - a

12/21/2016, 4:51 PMThanks everyone! - w

12/21/2016, 4:55 PM@adam-mcneilly and I think
operator close to a?
can be misunderstood as a null check (var
) or somethingname? - w
walmyrcarvalho
12/21/2016, 4:56 PMI think
is fineif - a
adam-mcneilly
12/21/2016, 4:57 PMOoh fair point there too. - a
adam-mcneilly
12/21/2016, 4:57 PMThoughts on doing if/else if on a single line? Is this like an accident waiting to happen? - w
walmyrcarvalho
12/21/2016, 4:58 PMNot sure how you could mess with a one-linerif - a
adam-mcneilly
12/21/2016, 4:58 PMI'm not getting a warning in AS... - a
adam-mcneilly
12/21/2016, 4:58 PMI typed it out to see if I would. - w
walmyrcarvalho
12/21/2016, 4:59 PMI don't think lint checks that as a wrong statement - a
adam-mcneilly
12/21/2016, 4:59 PMGotcha. - a
adam-mcneilly
12/21/2016, 5:05 PMSorry for another beginner question. I just did
but I'm not entirely sure why smart cast won't work here. I just checked that address isn't null, why do I have to unwrap it? Am I doing this wrong, or is this just how I have to do it?var hash = if (address != null) address!!.hashCode() else 0 - d
dh44t
12/21/2016, 5:06 PMis address a var?👍 1 - a
adam-mcneilly
12/21/2016, 5:06 PMit's a string - a
adam-mcneilly
12/21/2016, 5:06 PMif that matters - j
jw
12/21/2016, 5:06 PMaddress?.hashCode() ?: 0 - d
dh44t
12/21/2016, 5:07 PMif is a var, it means that could change in time and being set to null by another thread - a
adam-mcneilly
12/21/2016, 5:07 PMI defined it this way (or well, the AS conversion did)var address1: String? = ""
