I try to implement

LinkedList<E>

(from Java), but what Kotlin list should I extend?

ArrayList

is final, so can't use that, and just

List

makes me implement every method myself 😞 extending

MutableList

is even worse....

AbstractList

?

Thank you! That's what I was looking for. Now it forces me to implement

get(index: Int)

(and for mutable list a few more). Where do I get/save those values? Just create another list in a property of it?

What values? (Also, I recommend extending

AbstractCollection

for a linked list).

The values for the list....

Return the element at that index in the list.

Obviously, but how to get that, as I can't use

this.get(index)

as that's the method I am implement, where is the data stored?

You need to implement that part, you decide

But to save the data, I have to implement another list right? But eventually there has to be a list that saves data by itself instead of wrapping another list. Wonder how this list saves its data

Look at the source for

java.util.LinkedList

Not the worlds best example of an implementation but this https://github.com/touchlab/Stately/blob/master/src/commonMain/kotlin/co/touchlab/stately/collections/SharedLinkedList.kt
