Equivalent of getClass() for KClass in Kotlin
In this article, we will take an example and demonstrate how we can obtain the class reference in Kotlin. Kotlin does not support fetching the class reference directly, but you can obtain the same reference via extension itself. In the following example, we will see how we can do it via Kotlin library functions.
Example – Class reference using KClass
In this example, we will get the reference of the class.
import kotlin.reflect.KClass
fun main(args : Array<String>) {
// to get the reference of the class
fun<T: Any> T.getClass(): KClass<T> {
return javaClass.kotlin
}
val myVariable = "String"
val myAnotherVariable = 1
// As the variable is of String type,
// it will give us java.lang.String
println("Kotlin type: ${myVariable.getClass()}")
// this is of type Int
println("Kotlin type: ${myAnotherVariable.getClass().simpleName}")
}Output
On execution, it will yield the following output −
Kotlin type: class kotlin.String Kotlin type: Int
