basically I want to write some code that produces some values, and use a Consumer (or whatever) to separate the processing part |
| 14:27 |
|
aditsu_ |
one possible use is to collect them into a List |
| 14:28 |
|
aditsu_ |
java 8 has Consumer and Collectors.toList, but they seem to be unrelated |
| 14:28 |
|
aditsu_ |
how can I use a Collector as a Consumer? or is there a Consumer that just puts things into a List? |
| 14:34 |
|
pdurbin |
aditsu_: you're starting to play with Java 8? |
| 14:34 |
|
aditsu_ |
I started a few months ago, but haven't done a lot |
| 14:37 |
|
pdurbin |
the main thing I've done is work through these exercises (which I recommend): https://github.com/stuart-marks/LambdaHOLv2 |

sorry, disconnected |
| 14:39 |
|
aditsu__ |
you probably know I've been fiddling with javafx |
| 14:39 |
|
pdurbin |
aditsu_: did you see the github repo I linked? |
| 14:39 |
|
aditsu_ |
I see it now in the logs |
| 14:40 |
|
aditsu_ |
bah, github :p |
| 14:41 |
|
aditsu_ |
anyway, I'll check it out, but do you have any tips about my question? |
| 14:43 |
|
pdurbin |
aditsu_: there's a lot of .collect(toList()) at https://github.com/stuart-marks/LambdaHOLv2/blob/master/LambdaLab/test/solutions/Exercises.java |
| 14:44 |
|
pdurbin |
not sure if that helps |
| 14:44 |
|
aditsu_ |
pdurbin: I know how to collect a stream, but I don't have a stream here |
| 14:46 |
|
aditsu_ |
I would like to use a Consumer |
| 14:47 |
|
pdurbin |
hmm, well there's some IntConsumer in there |
| 14:48 |
|
aditsu_ |
oh, I think it's actually easy to just write it |
| 14:49 |
|
aditsu_ |
that is, a Consumer that collects to a List |
| 14:49 |
|
pdurbin |
aditsu_: you'll have to paste some code for us once you figure it out |
| 14:49 |
|
aditsu_ |
final List<Integer> l = new ArrayList<>(); |
| 14:49 |
|
aditsu_ |
final Consumer<Integer> c = l::add; |
| 14:49 |
|
aditsu_ |
I just tried that kinda randomly, and it actually worked :o |
| 14:50 |
|
pdurbin |
heh |
| 14:50 |
|
aditsu_ |
I use it like: c.accept(3); |
| 14:52 |
|
pdurbin |
we *just* switched to Java 8 in out last release. I should start playing with the new goodies |
| 14:53 |
|
pdurbin |
I've had this book since JavaOne 2014 (signed by the author!) and it seems good: https://github.com/java8/Java8InAction |
| 14:54 |
|
aditsu_ |
huh, IntConsumer is not a Consumer, but a similar class that accepts the primitive type int rather than Integer |
| 14:54 |
|
aditsu_ |
that seems to be a pattern in java 8 - they write separate classes/methods for different primitive types |
| 14:55 |
|
pdurbin |
definitely some consumer stuff in that book: https://github.com/java8/Java8InAction/search?utf8=%E2%9C%93&q=consumer |
| 14:57 |
|
aditsu_ |
I think they really went overboard with a lot of this stuff... but hey, it's java :p |

Is anyone here doing any Android development? |
| 15:16 |
|
aditsu |
I'm not actively doing it, but have some interest (and almost no experience) |
| 15:17 |
|
pdurbin |
I worked on https://github.com/IQSS/dataverse-android a year ago and haven't touched it since. |
| 15:17 |
|
pdurbin |
but my question is more about another app |
| 15:18 |
|
pdurbin |
one that I actually use: https://github.com/AntennaPod/AntennaPod |

pdurbin i am actually about to try a little dabble in android |
| 16:49 |
|
sfisque |
i did do a very trivial port of my old j2me palm app, but that was mostly a toy app. basically uses the local web services cross indexed with gps to find nearby bus/rail stops and tell you next arrivals |
| 16:51 |
|
sfisque |
i'm considering a mathy type game for my kids to play, this time around, something like a flash card game, simple with funny fx to engage them |
| 18:20 |
|
pdurbin |
sfisque: cool. My kids love this math game: https://www.prodigygame.com |
