Can a MutableList have items of two different (object) type? If not what are my alternatives?

mutableList<Any>

Do they have a common base class, use the base class instead of Any if so

@Sudhir Singh Khanger Note that there are very few cases where

List<Any>

is the right solution, feel free to share your code if you need some help

Thanks everybody. @cedric I am learning Kotlin by writing a Udacity Android Nanodegree project. I need to pass two simple model classes to a heterogeneous-RecyclerView Adapter. I am passing them as one MutableList. I am not very familiar with the collections class in Kotlin. That's on my list once I finish this sample app. https://github.com/sudhirkhanger/baking-app-kotlin
