I used the following code to write output to a file.
FileOutputStream fout = new FileOutputStream(fname,true);
PrintStream ps = new PrintStream(fout);
Random r = new Random(10);
for(int i = 0 ; i <= r1-1; i++)
{
for (int j = 0 ; j <= c1-1; j++)
{
m1[i][j] = r.nextInt(10);
//System.out.println(m1[i][j]);
ps.print(m1[i][j]);
ps.printf("\n");
}

//ps.printf("\r");
}
ps.close();
fout.close();
}


with this code if I read the output file in notepad I get all junk
characters written out. Like this:

ਲ਼ਰਲ਼ਰਸ਼ਸ਼

But if I open this file in textpad the output is fine:

3
0
3
0
6
6

However if I uncomment
//ps.printf("\r");

Output in notepad is surprising. There are no new lines: 303066

But textpad is fine !


Don't understand what is happening !?

Apparently TextPad considers \n a line break while NotePad only
considers \r\n a line break.

That explains the last phenomenon.

The first could be due to UTF-8 versus ISO-8859-1 issues.

You could try explicit specifying character set.

You need to use a Writer class to translate the output to text
your system understands. It is possible Textpad has some
auto-detection feature for the file's encoding and is
converting it automatically.

....

Maybe NotePad is interpreting a \r followed by another character other
than \n as a weird character?

Note that the line termination problem can be fixed very easily by
replacing 'ps.printf("\r");' with 'ps.printf("%n");'.

Your character encoding sounds like it is all messed up. Also the
newline character on most windows machines is \r\n.

you want to view the file in hex to see just what is in there.

What is happening is Windows defines the end of line as \r\n,
where as Unix defines the end of line as a single \n.

TextPad is detecting and reading the file as a Unix text file
where as Notpad only understands Windows so it displays it as
a single line because the line does not contain a Windows end
of line marker.
