How to write new line in Java FileOutputStream

Question

I want to write a new line using a FileOutputStream; I have tried the following approaches, but none of them are working:

encfileout.write('\n');
encfileout.write("\n".getbytes());
encfileout.write(System.getProperty("line.separator").getBytes());

Define "not working". – Reveal

its not writing new line – Hakim

@PavanPatidar: It is writing a newline. For sure. – Sough

Try executing encfileout.write("Fant".getbytes()); encfileout.write("\n".getbytes()); encfileout.write("astic".getbytes()); If you see the whole word on a single line your problem is confirmed. Especially, the encfileout.write(System.getProperty("line.separator").getbytes()); should work. – Palla

@Palla it is working on localhost but when i am deploying in on my server it does't works. – Hakim

It could be a viewer problem... Try opening the file in EditPlus or Notepad++. Windows Notepad may not recognise line feed of another operating system. In which program are you viewing the file now? – Palla

@Teddy:Thanks, you are right its viewing problem, notepad++ is showing correctly my data. Thanks again for bring my attention. – Hakim

@PavanPatidar I added the last comment as an answer... you can accept if it solved your problem. If you accept it, this question will be marked as answered. – Palla

Answer 2

This should work. Probably you forgot to call encfileout.flush().

However this is not the preferred way to write texts. You should wrap your output stream with PrintWriter and enjoy its println() methods:

PrintWriter writer = new PrintWriter(new OutputStreamWriter(encfileout, charset));

Alternatively you can use FileWriter instead of FileOutputStream from the beginning:

FileWriter fw = new FileWriter("myfile");
PrintWriter writer = new PrintWriter(fw);

Now just call

writer.println();

And do not forget to call flush() and close() when you finish your job.

I hope you don't mind that i added the missing charset parameter. – Reveal

@Pavan Could you explain why it's not what you're looking for so the answer can be amended/another answer provided? – Plain

FileWriter and PrintWriter are feature rich. The println() of Printwriter works great!!! – Onagraceous

Answer 3

To add a line break use

fileOutputStream.write(10);

here decimal value 10 represents newline in ASCII

Answer 4

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

fos.write(lineSeparator.getBytes());

Please consider adding some form of explanation with your answer. Code only answers are typically discouraged. – Kresic

Answer 5

You can use Fos.write(System.lineSeparator().getBytes()). it worked for me.
