when (obj) {
    null -> println("is null")
    else -> println("is not null")
}

I couldn't figure out how to check for not null instead.. is that possible? like !null -> 😄

If you have to use when:

when {
  obj == null -> println("is null")
  obj != null -> println("is not null")
}

Otherwise, it might be better to simply use if (obj != null) or perhaps, the null coalescing operator ?., depending on your use-case

Thanks!
