Saving File with new file name

Question

I am subclassing JFileChooser and implementing ActionListener for being able to save and open files.
I am using different file extensions (.ac and .ps), and when saving, I first check that the file name has the right extension.
If it doesn't, I add the right extension.
But for some reason it doesn't show my saved new file, even though in the debugger it goes through all the code of saving.
Here is the main portion of my code before the code of saving (adaptee is my JFileChooser):
File ananyaFile = adaptee.getSelectedFile();
String name = ananyaFile.getName();
int l = name.length();
if (!(l >= 4 && name.charAt(l - 3) == '.' &&
((adaptee.getFileFilter() == adaptee.acExtensionFilter &&
name.charAt(l - 2) == 'a' && name.charAt(l - 1) == 'c') ||
(adaptee.getFileFilter() == adaptee.psExtensionFilter &&
name.charAt(l - 2) == 'p' && name.charAt(l - 1) == 's'))))
if (adaptee.getFileFilter() == adaptee.acExtensionFilter)
name = name + ".ac";
ananyaFile = new File(name);
adaptee.setSelectedFile(ananyaFile);
else if (adaptee.getFileFilter() == adaptee.psExtensionFilter)
name = name + ".ps";
ananyaFile = new File(name);
adaptee.setSelectedFile(ananyaFile);
Why does it not show my saved new file? Do I have to set it somewhere else?
Thanks for your time!

Answer 1

Ok, I put the code which adds the extension
File ananyaFile = this.getSelectedFile();
if (ananyaFile == null)
   return;
String name = ananyaFile.getName();
int l = name.length();
if (!(l >= 4 && name.charAt(l - 3) == '.'  &&
   name.charAt(l - 2) == 'a' && name.charAt(l - 1) == 'c')  
   name = name + ".ac";
   ananyaFile = new File(name);
   this.setSelectedFile(ananyaFile);
}into the approveSelection method of my subclass of JFileChooser.
If someone wants to open a file without writing the extension and the file with the extension (which was added in my code) exists, it does get opened.
Also, if someone wants to save a file without writing the extension and the file with the extension (which was added in my code) exists, it does ask if you want to replace the file (as I have programmed).
But if you say yes, or if you want to save a file without the extension that doesn't yet exists (with the extension), it doesn't save it.
However, saving works fine if someone writes the full file name into the File name box.
Well, I would like to allow the user not to write the extension not only for opening a file, but also for saving a file.
Please help! I am getting pretty desperate! Thanks!
