Kotlin accessing Java class

Question

Why in Kotlin do you need to access they Java class of an object using

MyActivity::class.java

I have been told is something to do with Kotlin's interoperability with JS ... Any thoughts?

Answer 1

Because MyActivity::class returns a KClass<MyActivity> object. This is an extended object that is part of kotlin's expanded reflection capabilities. Since people also need to access the java class for backwards-compatibility it is included as the field java on the KClass object.
