problems with outputting to screen

[EscSequenceAlpha]

I've started the newboston java gmae developement tutorials and I have a problem, I've set the background to PINK but whenever I run it its actually black. can someone give an explaination and possible fix for why this might be the case?

package gameDevelopement;

import java.awt.*;
import javax.swing.JFrame;

public class Game extends JFrame
{
	public void run(DisplayMode dm)
	{
		// set window properties
		setBackground(Color.PINK);
		setForeground(Color.WHITE);
		setFont(new Font("Arial", Font.PLAIN, 24));
		
		// screen variable to use screen methods
		Screen screen = new Screen();
		try
		{
			// set full screen
			screen.setFullScreen(dm, this);
			try
			{
				// do nothing for 5 secs
				Thread.sleep(5000);
			}
			catch(Exception ex)
			{
				
			}
		}
		finally
		{
			// after 5 secs return to regular size
			screen.restoreScreen();
		}
	}
	
	public void paint(Graphics g)
	{
		// whenever you make a JFrame it calls the paint method automatically
		g.drawString("This is gonna be awesome", 200, 200);
	}
	
	public static void main(String[] args)
	{
		// in order to use displayMode method we need a display mode object
		DisplayMode dm = new DisplayMode(800, 600, 16, DisplayMode.REFRESH_RATE_UNKNOWN);
		// we need an object of this class for run method
		Game game = new Game();
		game.run(dm);
	}
}

package gameDevelopement;

import java.awt.*;
import javax.swing.JFrame;

public class Screen 
{
	//gives interface to graphics card
	private GraphicsDevice gc;
	
	public Screen()
	{
		//env contains all your graphics device objects
		GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment();
		//gives access to computer screen
		gc = env.getDefaultScreenDevice();
	}
	
	// convert window to full screen
	// DisplayMode contains 4 parameters (screen res x, screen res y, bit depth, refresh rate)
	public void setFullScreen(DisplayMode dm, JFrame window)
	{
		//no tool bars
		window.setUndecorated(true);
		//can not be resized
		window.setResizable(false);
		//converts window to full screen
		gc.setFullScreenWindow(window);
		
		// if graphics card is able to display those settings
		if( dm != null && gc.isDisplayChangeSupported())
		{
			try
			{
				gc.setDisplayMode(dm);
			}
			catch(Exception ex)
			{
				
			}
		}
	}
	
	public Window getFullScreenWindow()
	{
		return gc.getFullScreenWindow();
	}
	
	// return screen to normal
	public void restoreScreen()
	{
		Window w = gc.getFullScreenWindow();
		// if the window contains something
		if( w != null )
		{
			// free resources
			w.dispose();
		}
		// takes anything away from full screen
		gc.setFullScreenWindow(null);
	}
}

I've set the background to PINK but whenever I run it its actually black.

Read the API for JRootPane, which is the single child of a JFrame container (also see the API for the interface RootPaneContainer) and you'll easily see why.

Don't try doing any fancy stuff directly in the content area of any top level window. Base your GUI on a JPanel (or in comparatively rare cases, on another subclass of JComponent) and either add(...) that to the top level window or set it as the top level window's content pane.

Additionally, please post in an appropriate section. I'm moving this to AWT/Swing

I cant make that kind of judgement call, because swing topics can also be a subset of new to java.

this is bugging me

public void restoreScreen()
    {
        Window w = gc.getFullScreenWindow();
        // if the window contains something
        if( w != null )
        {
            // free resources
            w.dispose();
        }
        // takes anything away from full screen
        gc.setFullScreenWindow(null);
    }

I dont understand this... it looks like I've just created a variable w and immediately destroyed it? why... surely w would be a copy of the screen output but not the actual one thats executing.

wouldnt this be all I need?
gc.setFullScreenWindow(null);
