Kotlin Try Catch Return Result

Jul 25, 2018

try is an expression, i.e. it may have a return value:

val result: Int? = try { parseInt(input) } catch (e: NumberFormatException) { null }
val user = try {    signinUser(googleUserId)}catch (e: Exception) {    e.printStackTrace()    null}

You can also do

val finalName = name ?: throw IllegalArgumentException("Name required")
