When using Scala, if you ever need to list the subdirectories in a directory, or the files under a directory, I hope this example is helpful:
import java.io.File
object FileTests extends App {
// list only the folders directly under this directory (does not recurse)
val folders: Array[File] = (new File("/Users/al"))
.listFiles
.filter(_.isDirectory) //isFile to find files
folders.foreach(println)
}
If it helps to see it, a longer version of that solution looks like this:
