[code] public  Account temp(){
        String id2 = null;
        try {
            id2 = jTextField1.getText().toString().trim();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        System.out.println("ID2"+id2);
        String password = jPasswordField1.getPassword().toString();
        System.out.println("pw"+password);
