Canonical Path without an extension

[Jacky Luk]

   
 private void jMenuItem3ActionPerformed(java.awt.event.ActionEvent evt) {                                           
        // TODO add your handling code here:
     
           // TODO add your handling code here:
      JFileChooser  fileChooser = new JFileChooser();
        
        fileChooser.setFileFilter(new ExtensionFileFilter("png","png"));
        
         
         int returnValue = fileChooser.showSaveDialog(null);
        if (returnValue == JFileChooser.APPROVE_OPTION) {
             
                String selectedFile;
            try {
                selectedFile = fileChooser.getSelectedFile().getCanonicalPath();
                  chartCanvas.saveToPNG(selectedFile);
            } catch (IOException ex) {
                Logger.getLogger(bokss_patient_frame.class.getName()).log(Level.SEVERE, null, ex);
            }
                
              
        }
       
     
    }  

When I do this, the returned file name has no extension attached.
Any ideas how to fix it?
Thanks
Jack

You have to post a SSCCE. For example, the posted code doesn't have ExtensionFileFilter or chartCanvas.

Basically, we should be able to copy the posted code, compile straightaway and then we would be in a position to run and reproduce the problem in our machines. That would end in a quick resolution.

String concatenation?

Also, the JDK comes with a perfectly usable FileNameExtensionFilter. Have you been reinventing the wheel?

Why are you handling selected file as it is of type String ?

If you have JFileChooser#getSelectedFile() method that returns File, you can find out whatever you need to know about the file selected - including it's path, name with extension, etc.
