A better design would be to add these Components initially but disable them (setEnabled(false)). Anyway, to answer your question in the scenario you have, you should run your code on the UI thread, and revalidate and repaint after adding the new components

                if(JPasswordField.getPassword().equals(password){
                   SwingUtilities.invokeLater(new Runnable() {
                      public void run() {
                        panel1.add(pf);
                        panel1.add(button); //TO HERE IM HAVING A PROBLEM WITH
                        panel1.validate();
                        panel1.repaint();
                     }
                  });
                }
