Please explain why and does it mean.
I am using Microsoft Access 97

   // I am creating the table using the following method. 
   public void createTable () {
    Connection fConn= ConnForCont1.getInstance ().getConnection ();
    Statement stat= null;
    String SQL= null;
    SQL= "CREATE TABLE " +"NP" +" (Name CHAR(25), Password CHAR(25), Messages VARBINARY)";
    try {
      stat= fConn.createStatement ();
      stat.execute (SQL);
    }catch (SQLException ee){ System.out.println (ee); }
     catch (Exception ee){ System.out.println (ee); }
  } // createTable ()

        // I want to write the object also in the database
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        ObjectOutputStream oos = new ObjectOutputStream(bos);
          oos.writeObject("new User(" +name +"," +pass +")");
          oos.flush();
          oos.close();
        byte[] ser= bos.toByteArray ();
