How to write to a file with \n (new line)???

Question

Hi there,
I have the following method that reads a file's content and convert it into a string:
     public static String getFileContent(String fileName) throws IOException
          File file = new File(fileName);
          FileInputStream fileInputStream = new FileInputStream(file);
          BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(fileInputStream));
          StringBuffer stringBuffer = new StringBuffer();
          String line;
          while ( (line=bufferedReader.readLine()) != null )
               stringBuffer.append(line+"\n");
          return stringBuffer.toString();
     }I'm trying to write a method that writes a String to a file WITH THE NEW LINE. All classes I used (DataOutputStream, FileWriter, PrintStream...) do not force a new line (I get everything in one line)
I thought maybe I should change the "\n" in the line
stringBuffer.append(line+"\n"); but...didn't know what.
thanks for any advise

Answer 1

BufferedReader readLine remove the newline sequence. But you're putting \n back which should do what you appear to want.
However newline sequence isn't always just \n, on unix systems it's \n, on windows its \r\n (reads "carriage-return, linefeed"). Sytem.getProperty("line.separator"); will get you the appropriate end of line string.
