QuizCard txt file - newline missing

[Dinesh Kumar Tadepalli]

HI, When I ran and saved some cards in the quiz card game of head first java, I observed that a new line character is not working and all my cards are on line. I checked my txt file and it didn open in new lines

the specific code where i wrote into a file is:

	private void saveFile(File file) {
		try {
			BufferedWriter writer = new BufferedWriter(new FileWriter(file));
			for(QuizCard card:cardList) {
				writer.write(card.getQuestion()+"/");
				writer.write(card.getAnswer()+"\n");
			}
			writer.close();
		} catch (Exception ex) {
			System.out.println("Couldnt write the cardList out");
			ex.printStackTrace();
		}
	}

please point out the mistake.

thanks

It probably is working, but your platform doesn't recognize "\n" as a line separator. A good thing to do for cross-platform compatibility is:

    
String sep = System.getProperty("line.separator");

then

    
writer.write(card.getQuestion()+"/");  
writer.write(card.getAnswer()+sep);

Or perhaps use a PrintWriter object and use the println(...) method when you want to write a String followed by a line terminator.

Or the Formatter methods which are copied to PrintWriter#printf, PrintWriter#format and String#format. Use the %n tag.

thanks for your suggestions, but the String sep = System.getProperty("line.seperator"); does not work too.

should i include or import any package?

how to write using printWriter methods?

[Campbell Ritchie]

The most commonly used PrintWriter is called System.out.
