May be the following will help.

1. First u need to read your property file. See doc

   Properties properties = new Properties();
   try {
     properties.load(new FileInputStream("filename.properties"));
   } catch (IOException e) {
     System.err.println("Ooops!");
   }
   

2. Second add event handler to your window, which will save your data in property file.All that you need to save just put in properties instance and store it on exit

    addWindowListener(new WindowAdapter() {
     public void windowClosing(WindowEvent e) {
       try {
        properties.store(new FileOutputStream("filename.properties"), null);
       } catch (IOException e) {
       }
     }
   });
   

That's all, if I'd understood you correct)
