Hello sekitaka.

I was wondering how to write class name.class in java in Kotlin, so make a note of it.

Get static

You can use a class object by using :: class.java as shown below.

val jclass = String::class.java
val kclass = String::class.java.kotlin
println(jclass) // class java.lang.String
println(kclass) // class kotlin.String

Get from instance

Added based on the comment received by @meeniex. You can refer to it from the instance as follows.

val jclass = s.javaClass
val kclass = s.javaClass.kotlin 
println(jclass) // class java.lang.String
println(kclass) // class kotlin.String
