Line 1,521:
=={{header|Scala}}==
===Discussion===
The code will throw a <tt>NoSuchElementException</tt> if the file doesn't have 7 lines.
<lang scala>val lines = io.Source.fromFile("input.txt").getLines
val seventhLine = lines drop(6) next</lang>
===Imperative version===
Solving the task to the letter, imperative version:
Line 1,541 ⟶ 1,542:
}
if ("" == seventhLine) println("line is empty")</lang>
▲Functional version:
<lang scala>val file = try Left(io.Source.fromFile("input.txt")) catch {
case exc => Right(exc.getMessage)
