Best Way to Convert ArrayList to String in Kotlin

Question

I have an ArrayList of String in kotlin

private val list = ArrayList()

I want to convert it into String with a separ

Answer 1

Kotlin as well has method for that, its called joinToString.

You can simply call it like this:

list.joinToString());

Because by default it uses comma as separator but you can also pass your own separator as parameter, this method takes quite a few parameters aside from separator, which allow to do a lot of formatting, like prefix, postfix and more.
