What’s the Scala way for this type of read loop?

Dave Briccettit asked:

What’s the Scala way for this type of read loop?

My answer:

import java.io._
import scala.io._
import scala.collection.mutable._
object PropsParser{
  val state = HashMap.empty[String,String]

  // Run both ways, should print the same thing
  def main(args:Array[String]){
    load
    println(state)
    state.clear
    load2
    println(state)
  }

  // A more Scala-ish way? Could be memory hog
  def load2{
    val src = Source.fromFile(getFile)
    src.getLines.map(_.split("=")).foreach((kv) => state += kv(0) -> kv(1).trim)
  }

  // Dave's original way
  def load{
    val in = new BufferedReader(new FileReader(getFile))
    var line = in.readLine
    while (line != null){
      val kv = line.split("=")
      state += kv(0) -> kv(1)
      line = in.readLine
    }
    in.close
  }

  def getFile= new File("Some/path/to/your/props/file")

}
