fun createObjectByPackageName(packageName: String, className: String): Any? { try { val ...

# multiplatform

fun createObjectByPackageName(packageName: String, className: String): Any? {
try {
val fullClassName = "$packageName.$className"
val clazz = Class
return clazz.newInstance()
} catch (e: ClassNotFoundException) {
e.printStackTrace()
} catch (e: IllegalAccessException) {
e.printStackTrace()
} catch (e: InstantiationException) {
e.printStackTrace()
}
return null
}

is there a pure kotlin implementation of this ?

afaik there is no multiple exception catching like in Java (yet) (also not sure if that is your main question here)

i guess you could do something like this:

fun createObjectByPackageName(packageName: String, className: String): Any? {
    return try {
        Class
            .forName("$packageName.$className")
            .getDeclaredConstructor().newInstance()
    } catch (e: Exception) {
        when(e) {
            is ClassNotFoundException,
            is IllegalAccessException,
            is InstantiationException -> e.printStackTrace()
            else -> throw e
        }
        null
    }
}

or write your own multicatch extension 🤷

(disclaimer: i didn’t try this 😅 )
(also not sure how this is related to multiplatform?)

basically Class.forname is a java function we have been using the above function for a while now we are moving it kotlin multiplatform and apparently there is no alternative of this in kotlin 😞

Kotlin reflection is supported on JVM targets only.

yeah so far no alternative 😞
