How to read a file as a byte array in Scala

Question

I can find tons of examples but they seem to either rely mostly on Java libraries or just read characters/lines/etc.

I just want to read in some file and get a byte

Answer 1

I have used below code to read a CSV file.

import scala.io.StdIn.readLine
import scala.io.Source.fromFile

readFile("C:/users/xxxx/Downloads/", "39025968_ccccc_1009.csv")

def readFile(loc :String,filenm :String): Unit ={

  var flnm = fromFile(s"$loc$filenm") // Imported fromFile package

  println("Files testing")
  /*for (line <- flnm.getLines()) {
    printf("%4d %s\n", line.length, line)
  }*/
  flnm.getLines().foreach(println) // getLines() is imported from readLines.
  flnm.close() 
}
