You will need to implement FileFilter on the JFileChooser object.  Here is an example.  Try modifying it to fit your needs and then post back if you have any issues:
JFileChooser chooser = new JFileChooser();
       
          chooser.addChoosableFileFilter(new FileFilter() {
 
            @Override
            public boolean accept(File f) {
                if (f.isDirectory()) {
                    return true;
                }
                
                String extension = getExtension(f);
                if (extension != null) {
                    return ((extension=="rtf")?true:false);
                }
                
                return false;
            }
 
            @Override
            public String getDescription() {
                return "*.RTF";
            }
            
            String getExtension(File f) {
                String ext = null;
                String s = f.getName();
                int i = s.lastIndexOf('.');
 
                if (i > 0 &&  i < s.length() - 1) {
                    ext = s.substring(i+1).toLowerCase();
                }
                return ext;
            }
          });
          chooser.setAcceptAllFileFilterUsed(false);
         
          chooser.showSaveDialog(null);

This line disallows the "All Files" selection.  The FileFilter handles the inclusive extensions.
