How to declare a two dimensional ArrayList in Kotlin

[Victor Farkas]

Hi I'm new to Kotlin and I would like to declare an two-dimensional ArrayList (450/10) But it didn't work - tried different versions like

ArrayList>

or

arrayListOf(arrayListOf())

But it seems not the right one Can someone help me?

It is not clear what you are actually trying to do. But maybe one of the other collection classes would be a better choice: see kotlin.collections - Kotlin Programming Language[^].

I would like a data structure like this a b c d e f a b c d e f a b c d e f a b c d e f and would like to access [2][3]=c

It's all described in the Kotlin documentation at https://kotlinlang.org/docs/arrays.html[^].

It will be useful to try a code analysis tool, such as AppRefactoring
