Cooking and coding are fine!

Report a typo

You have your own small kitchen. As an engineer, you have discovered that classes for devices Microwave, MultiCooker implement the interfaces Logger (with a log() method) and Cooker (with a cook() method). For further engineering, you need to complete a generic class SmartKitchen that takes only the types which implement both Cooker and Logger. Complete its method finishCooking(), which takes allowed device and invokes log().

Write a program in Kotlin
// change the code below
class SmartKitchen<T> {

fun finishCooking() {
// finish the method
}
}

// don't change it!
interface Logger { fun log() }
interface Cooker { fun cook() }

class Microwave : Logger, Cooker {
override fun log() = println("Microwave finished cooking!")
override fun cook() = println("Microwave is cooking")
}
class MultiCooker : Logger, Cooker {
override fun log() = println("Multicooker finished cooking!")
override fun cook() = println("Multicooker is cooking")
}
