Kotlinでクラスオブジェクトを参照する(Javaのクラス名.classの代わり)

More than 1 year has passed since last update.

こんにちはsekitakaです。

javaでクラス名.classをKotlinではどのように記述すればよいのか迷ったのでメモしておきます。

staticに取得

以下のように::class.javaを使うことで、クラスオブジェクトを使う事ができます。

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

インスタンスから取得

@meeniex さん頂いたコメントを元に追記。
インスタンスからは以下のように参照できます。

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