How to read a file line by line and close it afterwards in Scala?

Question

Normally, they will tell you to

import scala.io.Source
for(line <- Source.fromPath("myfile.txt").getLines())
  println(line)

which seems to leave the file open. What is a closeable counterpart?

Answer 1

You can close the Source and this will close your file.

import scala.io.Source

val source = Source.fromFile("myfile.txt")
for (line <- source.getLines())
   println(line)
source.close()

Thanks, this answer distracted me. I keep wondering, why do you all guys use fromPath instead of fromFile? My compiler says that fromPath is not a member of Source and I must use fromFile instead. – Opinionated

"why do you all guys use fromPath instead of fromFile?" You are one of those guys. Tbh I just copied this from your question. Actually there is no such method. I fixed my answer to use fromFile. – Tacmahack
