i've been trying to get into 2D game programing
i started a tutorial on utube (java game programing)(the new boston channel)
PHP Code:
package bucky;

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

public class buckyy extends JFrame
{
    public static void main(String[] args)
    {
        DisplayMode dm = new DisplayMode(800,600,16,
                DisplayMode.REFRESH_RATE_UNKNOWN);
        buckyy b = new buckyy();
        b.run(dm);
    }

    private Screen s;
    private Image bg;
    private Image pic;
    private boolean loaded;

    public void run(DisplayMode dm)
    {
        setBackground(Color.green);
        setForeground(Color.red);
        loaded = false;
        load();
        s = new Screen();
        try
        {
            s.setFullScreen(dm, this);
            try
            {
                Thread.sleep(5000);
            } catch (Exception e)
            {
            }
        } finally
        {
            s.restoreScreen();
        }

    }

    public void load()
    {
        bg = new ImageIcon("bardejov.jpg").getImage();
        pic = new ImageIcon("p.png").getImage();
        loaded = true;
        repaint();
    }

    public void paint(Graphics g)
    {
        setBackground(Color.green);
        Graphics2D g2 = (Graphics2D) g;
        g2.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING,
                RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
        if (loaded)
        {
            g.drawImage(pic,0,0,null);
            g.drawString("LOL", 110, 200);
        }
    }
} 
this is the other class

PHP Code:
package bucky;

import java.awt.*;

import javax.swing.JFrame;

public class Screen
{
    private GraphicsDevice vc;

    public Screen()
    {
        GraphicsEnvironment env = GraphicsEnvironment
                .getLocalGraphicsEnvironment();
        vc = env.getDefaultScreenDevice();
    }

    public void setFullScreen(DisplayMode dm, JFrame window)
    {
        window.setUndecorated(true);
        window.setResizable(false);
        vc.setFullScreenWindow(window);
        
    try{
                vc.setDisplayMode(dm);
            }catch(Exception e){
                
            
        }
    }
    
    public Window getFullScreenWindow(){
            return vc.getFullScreenWindow();
    }
    public void restoreScreen(){
        Window w = vc.getFullScreenWindow();
        if(w != null)
            w.dispose();
        
        vc.setFullScreenWindow(null);
    }
} 
the problem is it's not working on win 7 , it just gives me full black screen with the String "LOL"
but no background color ... no images !!
but i tried the same code in wind XP and it worked !
