Create

This method is called once when the Application is started. In this method resources should be loaded and variables should be initialized.

Render

The method is called every frame, and is used to display whatever needs to be displayed. It is also used to update any variables/classes that may need to be updated, such as a camera.

Dispose

This method is called when the application is destroyed, and is used to free any resources, for examples Textures or the SpriteBatch. You will know that an object has to be disposed of if it implements the Disposable interface.

Pause

This method is called when the application is paused. Usually when the application looses focus.

Resume

This method is called when the application should be resumed. Usually when the application regains focus.

Main Game file

class Tutorial extends Game {
    
    public ScreenNumberOne screenNumberOne;

    public void create(){
        screenNumberOne = new ScreenNumberOne(this);

        this.setScreen(screenNumberOne);
    }

    public void render() {
        super.render();
    }
}

That is the basic file to allow you to make multiple screens. Notice that it extends Game.
