the types are so dank, for example:

static <T,K> Collector<T,?,Map<K,List<T>>> groupingBy(Function<? super T,? extends K> classifier)

you could almost generate the method body automatically from that, it tells you exactly what it does

yeah what i definitely need is a terminal that emulates flickering, static, and a crt's curvature. thanks for the suggestion.

please tell me why the gently caress there's a ? in Collector<T,?,Map<K,List<T>>>

(i know why, it's for muh parallel streams, and it shits up the api)

at some point when i'm not a burned out simmering husk of nasty attitude i'll have to sit down and have a good look at kotlin, seems pretty cool. like scala except actually planned out ahead of time.

i used to write a lot of ocaml so i'm quite comfortable with functional programming, which is probably why that type looks nice to me, instead of like noise

kotlin is cool, i know a guy who worked on its type system

java desperately needs either async/await or coroutines, this isn't 2010 any more

neither of which are java 9 features so idk maybe we'll get them in java 10 some time around the middle of trump's second term

javascript has async/await now. just use that instead.

java enums are real good cause they can have additional fields and methods and other stuff and are effectively just static classes with a list of static instances that the compiler understands.

Java enums are really good

C# gave all that up for ... the ability to use them as bitflags, lol (a problem that Java solved with EnumSet)

well you have to know java generic type syntax which takes some practice. let me try to explain in english:

code:

static <T,K> Collector<T,?,Map<K,List<T>>> groupingBy(Function<? super T,? extends K> classifier)

groupingBy(classifier) is a function that works for any type T and any type K. it requires as argument another function, the classifier, which is contravariant in the input type T and covariant in the output type K, according to God's Law (google those *variant words if you want to know why, they'll explain it better than me). the output of groupingBy is a Collector for Ts that returns a Map whose key type is K and value type is List of Ts. so basically, this function gets iterated over all the elements in a stream of Ts, and it takes each element t and calls classifier(t) on it. the result of this call is used as a key, and t itself is the value, and we stick those in a Map, appending the value to the List of Ts associated with that particular K.

specifically, you do something like this:

code:

Map<Integer, List<Dong>> x = dongs.stream().collect(groupingBy(Dong::getLength));
