PrintWriter and Batch Processing

[Sharp Tool]

Hi

I have a program that I call repeatedly with Java.
The program will analyse data and write a line of results to a text file.
I would like to keep writing to the same file.
How can this be done?

Tried:
Everytime I create a PrintWriter and pass the filename to it, it will
rewrite previous data - its starts off from scratch again.

Help is appreciated.

Cheers

The constructor FileOutputStream(File file, boolean append) may be what
you're looking for.
