Hello I have a class like this :

class MyResponse : ArrayList<MyResponseItem>

How do I create an object of MyResponse with a list of MyResponseItem?

[Joan Colmenero]

I have a way, but I do not know if that's the correct/cleaner way...

I've created a val like

val myResponse = MyResponse().apply{addAll(responseItemList}

[Michael de Kaste]

class MyResponse(
    list: List<String> = emptyList()
) : ArrayList<String>(list){
    
}

[Michael de Kaste]

val myResponse = MyResponse(listOf("some", "string"))

In general, you should prefer composition over inheritance. So the advice above is correct, but ask yourself if you need a class at all or if you can just use List<MyResponseItem> directly.

typealias is probably better 🙂
