Question

I am looping over the following lines from a csv file to parse them. I want to identify the first line since its the header. Whats the best way of doing this instead of making a var counter holder.

var counter = 0
for (line <- lines) {
  println(CsvParser.parse(line, counter))
  counter++
}

I know there is got to be a better way to do this, newbie to Scala.

Try zipWithIndex:

for (line <- lines.zipWithIndex) {
  println(CsvParser.parse(line._1, line._2))
}

@tenshi suggested the following improvement with pattern matching:

for ((line, count) <- lines.zipWithIndex) {
  println(CsvParser.parse(line, count))
}
