Is there an kotlin equivalent of ?: java operator?

Reluctant kotlin newbie here.

Is there an kotlin equivalent of ?: java operator?

I tried searching on google. Most results talk about ?: (elvis operator) in kotlin.

Looking for a way to write this in kotlin:

//java example
//return condition ? a : b;

The nicest way to do it is this: 

return when {
    condition -> a 
    else -> b
}

The Kotlin equivalent is:

if (a) b else c

That's the closest to the Java that you can get at this point.

? : is a tenary operator which is currently not present in Kotlin. There are few discussions on adding this operator to the language e.g. KT-5823 Support ternary conditional operator 'foo ? a : b' .

The usual suggestion is to use an if statement as replacement.

kotlin doesn't have ternary operator, but you can use if, when, try catch as expression

return if (condition) a else b
