I do not know if there will be a good practice for this, since I have a screen with a JMenu with many items
->Menu
->Usuario
{
->Iniciar sesion
->Registrarse
->Informacion de usuario
}
->Ayuda
{
-> Instrucciones de juego
-> Acerca del juego
}
Then I create a JFrame Form for each of these if necessary, registration window, login window, information window, help window, etc. And I do not know if this is a common practice or there is a more practical way to work this.
