Best way to represent a readline loop in Scala?

Question

Coming from a C/C++ background, I\'m not very familiar with the functional style of programming so all my code tends to be very imperative, as in most cases I just can\'t se

Answer 1

To add how the same can be achieved using the formerly new nio files which I vote to use because it has several advantages:

val path: Path = Paths.get("foo.txt")
val lines = Source.fromInputStream(Files.newInputStream(path)).getLines()

// Now we can iterate the file or do anything we want,
// e.g. using functional operations such as map. Or simply concatenate.
val result = lines.mkString

Don't forget to close the stream afterwards.
