Groovy write to file (newline)

Question

I created a small function that simply writes text to a file, but I am having issues making it write each piece of information to a new line. Can someone explain why it puts

Answer 1

As @Steven points out, a better way would be:

public void writeToFile(def directory, def fileName, def extension, def infoList) {
  new File("$directory/$fileName$extension").withWriter { out ->
    infoList.each {
      out.println it
    }
  }
}

As this handles the line separator for you, and handles closing the writer as well

(and doesn't open and close the file each time you write a line, which could be slow in your original version)
