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());

Answer 1

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.

Answer 2

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?

Answer 3

To add a line break use fileOutputStream.write(10); because decimal value 10 represents newline in ASCII

Answer 4

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

fos.write(lineSeparator.getBytes());
