Create a new line in Java's FileWriter

The Solution to Create a new line in Java's FileWriter is

If you want to get new line characters used in current OS like \r\n for Windows, you can get them by

  • System.getProperty("line.separator");
  • since Java7 System.lineSeparator()
  • or as mentioned by Stewart generate them via String.format("%n");

You can also use PrintStream and its println method which will add OS dependent line separator at the end of your string automatically

PrintStream fileStream = new PrintStream(new File("file.txt"));
fileStream.println("your data");
//         ^^^^^^^ will add OS line separator after data 

(BTW System.out is also instance of PrintStream).
