Java Adevnture Game

I am writing a adventure game in Java, I got a problem that usually there are many different screen in the game e.g the opening screen to start the game, then may be some screen to tell the story, then turn to the main game screen showing HP etc. How can I write these classed? I mean, do I need to write them in different class, using the MAIN to call them or just everytime redraw it?
