saving an output file

Hi,

Is there any way to save the output file to a user specified directory?
I would like for the user to be able to select a directory and save the
output file there. At the very least, is there any way to specify where
the file is saved by writing it into the code. I know that in C++ you
can specify where the file is created by doing something like this
"C:\\mydir\myprogram.cpp" when you name the file. Does Java allow
something like this?

See FileDialog[1] or JFileChooser[2].

In javax.swing, there is a class called JFileChooser (with the
possibility to select a directory instead of a file), and the other
Windowing-Frameworks provide a similar functionality, I guess.

For saving the File, java.io will help.

Ciao,

Look at documentation about

javax.swing.JFileChooser;
javax.swing.filechooser.FileFilter;

Yes. By using "test.txt" you use the current directory. "C:\\mydir\\test.txt"
specifies the absolute filename.

Greetings, Leon.
