how do we access Java collection APIs like

Queue

in Kotlin Multiplatform?

you can't

So for collections like a Queue, what would be the alternative to use in KMP?

ArrayDeque: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-array-deque/

java.util.Queue is not quite the same as kotlin.collections.ArrayQueue: the former has non-blocking offer/poll methods

If you want to use a Queue to send objects across threads (blocking queue of requests), the multiplatform equivalent would be KotlinX coroutines' Channel

@ephemient In what sense offer/poll are non-blocking?

Queue.offer

method docs only mention the behavior regarding capacity-restricted queues. For unbounded queues

offer

should be equivalent to

add

. And for

poll

there's a direct equivalent in `ArrayDeque`:

removeFirstOrNull
