How to write/insert lines in a file from top

Question

I am opening a writing to a file as follows:
(part of the code which does so)
FileOutputStream file; // declare a file output object
PrintStream r;
file = new FileOutputStream("filename") + ".properties",true);
r = new PrintStream( raj);
r.println ( value + "=" + data.getString(value) );
r.close();
This prints in file line after line like
A
B
C
How can I make it to print/insert new line right at the top ?
That is if I print A, then B, then C, how can I make it to get
C
B
A
in the file ?
Help is much appriciated.

Answer 1

Use a RandomAccessFile then you can position the
cursor anywhere in the file.Yes, but that still doesn't allow data to be inserted unless all following data is shifted to make room for the insertion. (If you don't shift, the inserted data will overwrite following data already there.)
