In runtime it shows Int
but in static it is Any

for a
, so both static and runtime type will be Int
. But take this more complicated example:
fun iReturnAny(): Any = 3
val a = iReturnAny()
Compiler will infer Any
for a
(because iReturnAny()
returns Any
), but runtime type will Int

. The static type will always be Any
, but the runtime type could be String
(if there is a string in there) or anything else.Ayden

- What type does a
have? Well, it's an Int
, "obviously", so let's "type that for you":
val a: Int = 3
