Found it - <https://antonioleiva.com/sealed-classes-kotlin/>

It’s starts by saying that there are no sealed classes in java, but <http://www.drmaciver.com/2007/09/how-to-create-sealed-classes-in-java/> seems to suggest otherwise. Where’s the catch?

I could look further, but just looking at this code sample, Antonio could be correct - While you can simulate a sealed class in Java, it doesn't look like it's caked into the language.

<@U0B84UUTV> is in this slack, perhaps he can answer.

yeah, Java doesn’t have the concept of “sealed class” meaning that the compiler can’t detect for you that you’re missing a check in a “switch” for example

at least from what I know from Java (the Java that can be used in Android)

Thanks for the article and the clarification.
