The
readTextandwriteTextmethods call theusemethod on the Input and OutputStream. (See: https://github.com/JetBrains/kotlin/blob/30788566012c571aa1d3590912468d1ebe59983d/libraries/stdlib/jvm/src/kotlin/io/FileReadWrite.kt#L108)According to the documentation this method automatically closes the object afterwards. https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.io/use.html
So there is no need to close it manually.
