Answer 1

Kotlin 1.3 provides Extension Function to ease the task.

Usage:

val strBuilder = StringBuilder()
strBuilder.appendln("some text")

In Kotlin 1.4 appendln() is deprecated and appendLine() is introduced.

Usage:

val strBuilder = StringBuilder()
strBuilder.appendLine("some text")

In Kotlin 1.4 appendln() is deprecated and has been replaced by appendLine(). – Tramel

I don't like extension functions whose name is longer then the string they replace. – Darbies
