Question

From the following code :

import java.io.*;

class fileTester {
  public static void main( String args[]) throws IOException {
    String string = "Suhail" + "\n" + "gupta";
    FileOutputStream fos = new FileOutputStream( new File("break.txt"));
    byte[] data = string.getBytes();
    fos.write( data );
    fos.close();
  }
}

I expected the output to be :

Suhail

Gupta

int the file created (i.e both the strings in a new line ) but the output is in a single line. Suhail gupta

Why is it so when i have used \n character in between the 2 Strings ?

Answer 1

You shouldn’t hard-code the new line character when writing to a file. Use the OS-specific newline String instead:

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

Also, rather than use a FileOutputStream to write raw bytes to a text file, why not wrap it in a PrintStream object so you can easily just use println(…) to do your newlines for you?
