Java SE (Java Platform, Standard Edition)

Hi

How do I add the correct extesion (ex,: .txt or .zip) If I have multiple filefilters.

Code Example:

//Create a file chooser
      JFileChooser fc = new JFileChooser();
      //Add File extensions *.txt, *.zip
      ZipFileFilter zipFilter = new ZipFileFilter();
      fc.addChoosableFileFilter(zipFilter);
      TxtFileFilter txtFilter = new TxtFileFilter();
      fc.setFileFilter(txtFilter);
      fc.setAcceptAllFileFilterUsed(false);
      
      
      int returnVal = fc.showSaveDialog(this);
        if (returnVal == JFileChooser.APPROVE_OPTION) {
          File file = fc.getSelectedFile();
        .....
       }

Where shoud I add .txt or .zip?

Regards
Suvi
