Question

So when I write to my text file using FileOutputSstream I have used both

fos.write(("0"+"\n").getBytes());

and

fos.write(System.getProperty("line.separator").getBytes());

and neither of them work… they still print on the same line…

Any thoughts?

Answer 1

use a PrintStream

System.out is a PrintStream for example.

You say you have a FileOutputStream. Then,

FileOutputStream f = new FileOutputStream("test.txt");
PrintStream ps = new PrintStream(f);
ps.print("line1");
ps.println(); //this writes your new line
ps.print("line2");
ps.close();

also you can use;

BufferedWriter fos = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(filename)));
      fos.write("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
      fos.newLine();
