JFileChooser Hide file type

How can I hide certain files in a JFileChooser control? This is what Im using so far but I can still see files I dont want to see.

Code:

---

    JFrame frame = new JFrame();
         
         
            String filename = "Desktop";
    JFileChooser fc = new JFileChooser(new File(filename));
   
   
   
      fc.setFileFilter(new FileFilter() {
  public String getDescription() { return "CSV files"; }
  public boolean accept(File f) {
      if(f.isDirectory()) return true;
      if(f.getName().endsWith(".csv")) return true;
      return false;
    }
  });
 

   
    // Show save dialog; this method does not return until the dialog is closed
    fc.showSaveDialog(frame);
  cFile = fc.getSelectedFile();

Can you explain a little more? I don't know what files you don't want to see and what it's showing up.

I tried this code:

Code:

---

            public void actionPerformed(ActionEvent e)
            {
                JFileChooser chooser=new JFileChooser();
                chooser.addChoosableFileFilter(new FileFilter(){

                    public boolean accept(File f)
                    {
                        if(f.isDirectory())return true;
                        else if(f.getName().endsWith(".csv"))return true;
                        else return false;
                    }

                    public String getDescription()
                    {
                        return "Comma separated file";
                    }
                });
                if(chooser.showOpenDialog(null)==JFileChooser.APPROVE_OPTION)
                {
                    //Do your things
                }
            }

and it works
