Scala - creating multiple files

Question

I am trying to create multiple files. For example, t1.txt, t2.txt, etc. I was thinking of something like code below, but it doesn't work:

 val nbFiles = 15
 for(n <- 1 to nbFiles) {
     val writer = new PrintWriter(new File("t$n.txt"))
     writer.write("Hello Scala")
     writer.close()
 }

I need a for loop for making some process on each file.

You need to interpolate the string by preceding it with an s:

val writer = new PrintWriter(new File(s"t$n.txt"))
                                      ^
