Create a new line in Java's FileWriter
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).
Try System.getProperty( "line.separator" )
writer.write(System.getProperty( "line.separator" ));
Try wrapping your FileWriter
in a BufferedWriter
:
BufferedWriter bw = new BufferedWriter(writer);
bw.newLine();
