Question

I am trying to write a file line by line using apache FileUtils.writeLines()
When I try to open the file (notepad++, editplus) it is with no line breaks.
(I am sending null to the encoding)
thanks.

FileUtils.writeLines(new File(INDICES_AND_WEIGHTS_FILENAME), indicesAndWeightsParams.indicesParams,";");

where indicesParams is a list
public List indicesParams;

Are you using code similar to this?

List<String> ls = new ArrayList<String>();
ls.add("aaa");
ls.add("bbbbb");

FileUtils.writeLines(new File("newfile.txt"), "UTF-8", ls);   // same effect as with "null" as encoding

After this code, newFile.txt does have newlines.

Using od -a newfile.txt generates (on Windows):

0000000   a   a   a  cr  nl   b   b   b   b   b  cr  nl
0000014

which shows that newlines really do exist.
