File reading in Kotlin, FYI

gistfile1.txt

//  Java code
BufferedReader br = null;
br = new BufferedReader(new InputStreamReader(assetManager.open(actualFilename)));
String line;
ArrayList<String> labels = new ArrayList<String>();
while ((line = br.readLine()) != null) {
    labels.add(line);
}
br.close();

//  Kotlin code
val labels = ArrayList<String>()
val inputStream = am.open(fileName)
inputStream.bufferedReader().useLines {
  lines ->
  lines.forEach {
      labels.add(it)
  }
}
