Functional Kotlin

The Any type

All types in Kotlin extend from the Any type (hold on a second, actually this isn't true but for the sake of the explanation, bear with me).

Every class and interface that we create implicitly extends Any. So, if we write a method that takes Any as a parameter, it will receive any value:

fun main(args: Array<String>) {        val myAlmondCupcake = Cupcake.almond()        val anyMachine = object : Machine<Any> {      override fun process(product: Any) {        println(product.toString())      }    }        anyMachine.process(3)        anyMachine.process("")        anyMachine.process(myAlmondCupcake)    }

What about a nullable value? Let's have a look at it:

fun main(args: Array<String>) {        val anyMachine = object : Machine<Any> {      override fun process(product: Any) {        println(product ...
