quick demo of reading csv data and mapping to a value object before printing out a property on each object

readfile.scala

import scala.io.Source

// value object - automatically implements equals and gethashcode
case class Line(lineNo: Int, partNo: String, title: String, description: String) 

object Test {

	// converts string array into Line value object
	def toLine(args: Array[String]): Line = {
		Line(args(0).toInt, args(1), args(2), args(3))
	}

	def main(args: Array[String]): Unit = {
		
		// read lines, convert each line to a Line value object, then print out part numbers
		val file = Source.fromFile("data.csv")
	  	file.getLines().map(str => toLine(str.split(", "))).foreach(l => println(l.partNo))
	  	file.close()
	}
