In Kotlin 1.3.30 bytecode targets for JVM versions 9, 10, 11 and 12 were added https://blog.jetbrains.com/kotlin/2019/04/kotlin-1-3-30-released/ The blog post states that

Note that so far newer versions don’t add any bytecode optimizations or features beyond the ones that exist in lower versions, but that is going to change in the future.

Does this mean that the JVM itself does not have any optimizations or is it only the Kotlin generated bytecode that loses out on these optimizations for those versions?

Most of the proto->kt options use protoc to create 1:100x Java LOC, then a wrapper in kt. Is anyone aware of a utility that converts proto->kt directly, preferably using kotlinx.serialization?

I'm getting null exceptions. Tracked it down to the fact that decripted returns (null, null)

Has anyone ever used this library that can prove the comparison to be true?

Why is there no smart cast in this case?

val s: CharSequence = "Whatever"
assert(s is String)
println(s.compareTo("Something")) // Unresolved reference compareTo

How do I get this to work without implementing the 100 functions it requires that I won't use?

is there a nice way to only take x elements from a sequence if x >= 0, otherwise return everything? Thinking of an extension function atm

regarding generics: if my type extends CrudRepository<X, Y> why is the type not within bounds when I use T: CrudRepository<X, Y>

And I dont understand why the IDE says a Nothing is required

Does anyone else’s company not let them use !! anywhere, no exceptions?

Is there a simple functional way to receive a non-nullable values map?

Is there a visibility modifier between public and internal? This is for a library project with many gradle modules. API usage is meant only for all modules and not external consumers.

Hi #general, I'm a lead mobile app developer at GE Lighting connected home team. I'm currently evaluating Kotlin Native multi-platform offerings. is there a #multiplatform channel where I can ask questions? or is it fine in here?

Is there a kotlin database library with support for coroutines? Not for android.

I don't understand why there is that error

Any kotlin-springboot users?

Why it isn't possible to use

*doubleArrayOf(1.0, 2.0)

?

In the kotlinx immutable collections library (https://github.com/Kotlin/kotlinx.collections.immutable), what is the difference between the persistent classes vs immutable classes?

Hi, Is someone looking for a kotlinconf ticket (Copenhague) ?

so can call it like:

fun getFoo(): Foo? {
// lookup logic for foo
  return foo?. someName { nullFunc = { <http://log.info|log.info>{"didn't find it"} }, nonNullFunc = { <http://log.info|log.info>{"Found $this"}} }
}

hello this probably have been asked a million of times how do i efficiently transform a pair into a map.entry asking for a friend 😉

i managed it by doing this

internal class MapEntry<K, V>(override val key: K, override val value: V) : Map.Entry<K, V>
internal fun <K, V> Pair<K, V>.toEntry() = MapEntry(first, second)

Hello! I want to use ExperimentalStdlibApi. But compiler ask me mark each usage with this annotation. Is it possible to set some option in multiplatform gradle to allow usage of experemental api without annotating own functions that use it?

Hi, is there a channel for new kotlin users to ask questions about setting up their environment? I'm having some issues with the create-react-kotlin-app command

Hey everyone. I have a question about Reflection: How to check if a class has overridden a default method from an interface? I have an interface with a default method, and two classes which implement this interface. One of the classes overrides the default method, and the other does not.

interface MyType {
  fun giveHello(): String = "Hello!"
}

class Polite: MyType {
  // Does not override giveHello()
}

class Rude: MyType {
  override fun giveHello(): String = "I don't like you"
}

I get access to the

giveHello

method using reflection like this:

val methodOfPolite = Polite::class.java.getDeclaredMethod("giveHello")
val methodOfRude = Rude::class.java.getDeclaredMethod("giveHello")

There's one weird thing here. The polite class does not override the

giveHello

method, but the

declaringClass

property of this method object still points to the class Polite. So is there a way I can check whether the class actually did override the default interface method or not? My use case looks something like this (assuming we can get the behaviour I'm asking for in a property called

isOverriden

):

if (methodOfPolite.isOverriden) {
  // do something
} else {
  // do something else
}

Here's a link to the question on StackOverflow: https://stackoverflow.com/questions/58047229/how-to-check-if-a-class-has-overriden-a-default-method-from-an-interface-using-r/58047393
