You could use

joinToString

which will handle that (and the trailing

\n

) for you.

val listOfDouble = listOf(1.0)
        val listOfInt = listOfDouble as List<Int>

        val first = listOfInt[0]

        System.out.println("first=$first (${first.javaClass.name})")

Anyone know why this even works ? ☝️

I would expect a

ClassCastException

or some runtime error

Hmm. Generics always need implicit casts at the callsite because of erasure, but it's funny that it happens to succeed in this case.

What’s the recommended way of calling a

suspend

fun from Java? I’ve been looking at different options mentioned here, but from my local testing I’m not receiving the callback in the

resumeWith

method (never called).

Hi everyone!

I have questions related to exceptions handling with sealed class.

But, what happen lets say if you have many caller and callee that barely have the same sealed class signature but with different object types.
