How to clone object in Kotlin?

Question

The question is that simple.

Kotlin documentation describes cloning only in accessing Java and in enum class. In latter case clone is just throwing an exception.

Answer 1

Here is a consistent solution that works for any object type:

Kotlin's Array data structure provides a clone() method that can be used to clone the contents of the array:

val a = arrayOf(1)
//Prints one object reference
println(a)     
//Prints a different object reference
println(a.clone())

As of Kotlin 1.3, the clone method has been supported on all major targets, so it should be usable across platforms.
