   private static void store() {
        Hashtable h = new Hashtable();
        h.put("A", "chiru");
        h.put("B", "Nag");
        h.put("C", "Venki");

        try {

            FileOutputStream fileOut = new FileOutputStream("hello.txt");
            ObjectOutputStream out = new ObjectOutputStream(fileOut);



        } catch(FileNotFoundException e) {
        } catch (IOException e) {
     private static void fetch() {

       Hashtable h = null;

       try {

           FileInputStream fileIn = new FileInputStream("Hello.txt");
           ObjectInputStream in = new ObjectInputStream(fileIn);

           h = (Hashtable)in.readObject();


       } catch (ClassNotFoundException e) {
       } catch(FileNotFoundException e) {
       } catch (IOException e) {

       for (Enumeration e = h.keys(); e.hasMoreElements(); ) {
           Object obj = e.nextElement();
           System.out.println(" Values: " + h.get(obj));

The use of Enumeration is a bit of old style, foreach is better.
