How do I write a new line character to a file in Java?

Using carriage return and line feed \r\n, a new line character can be written to a file. Two characters \r\n combined represent a new line on Windows whereas on Linux, \n represents new line.

  String robotsTxt = "User-Agent: * "+
    		"\r\nAllow: /"+
    		"\r\nSitemap: http://www.javapedia.net/sitemap.xml";
    File batFile= new File("robots.txt");
    PrintWriter batOut = null;
	try {
		batOut = new PrintWriter(batFile);
	} catch (FileNotFoundException e) {
		e.printStackTrace();
	}
    batOut.print(robotsTxt);
