This code produce runtime err “IllegalArgumentException: Callable expects 1 arguments, but 0 were provided”:
fun main(){
val name = "slon"
class Slon{
override val toString = name
}
Slon::class.primaryConstuctor!!.call()
}
Could you provide more clear err msg or fix this err?
the call method has a “varargs” parameter, so you need to pass at least a parameter.
passing a null parameter should solve the issue:
Slon::class.primaryConstuctor!!.call(null)
I think the error message is clear, because the call method is defined in KCallable class .
btw, the following line in your code doesn’t seem correct: override val toString = name
shouldn’t it be override fun toString() = name
?
