I am developing an application where the valid user gets access to the main application. But a problem arises when I run main class. The LoginFrame and Main(Editor.java) Frame start simultaneously. I want to first validate the user and then direct the user to the main application. I am calling Loginform.java from my main application (i.e Editor.java)

java.awt.EventQueue.invokeLater(new Runnable() {

        public void run() {
             new Login().setVisible(true);
    {
         Editor x =   new Editor();
         x.setVisible(true);
    }
        }
    });
