Hi everyone - sorry if i'm not posting in the right place, i'm new here Jamie, live in Galway, Ireland - been experimenting with Kotlin for a short while now loved Java for years and still use it alot but loving the less-verbose and sexier Kotlin syntax anyway, I have a question about casting a value from a java method to a HashMap and i've exhausted my google-fu 😕 calling

getAttribute("something")

on an instance of

com.sun.net.httpserver.HttpHandler

and I need to cast it to

HashMap<String, Any>

but i'm unfamiliar with how to do that

ah it can check at runtime? cool. thanks

yep, more or less same as in Java

okay so

val parameterMap = ex.getAttribute("parameters") as HashMap<String, Any>

isn't giving me any grief in the IDE anyway 🙂

that would work in most cases, but will break down if the attribute is null or not there at all

it's a little weird still, thinking I want to not use nulls but i'm going to have to while i'm using java classes I think

We usually react with 👍 here.

ah fair enough. only asking since the python and cfml slacks have a bot that lets you give awards to people and it keeps a score of who's most helpful and stuff.

Let's leave measuring "usefulness" on stackoverflow 🙂.
