Thread: Does this look ok for a game layout?

I wasn't sure where to post but this is the closest. I would just like to get some opinions on this game layout code before I start. Just in case I may have forgotten something important before I start. Thanks

The class that is run from a browser or in a jar file in a local system:

import java.awt.Dimension;
import javax.swing.JApplet;
import javax.swing.JFrame;
 
 
@SuppressWarnings("serial")
public class Game extends JApplet
{
 
	public Game()
	{
		setLayout(null);
	}
 
	public void init()
	{
		add(new Screen());
	}
 
	public static void main(String [ ] args)
	{
	      JFrame frame = new JFrame("Game");
	      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	      frame.setMinimumSize(new Dimension(800, 600));
	      frame.add(new Screen());
	      frame.pack();
	      //frame.setResizable(false);
	      frame.setVisible(true);
	}
 
}

And the screen (Basically the mainframe of the game):

import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Rectangle;
 
import javax.swing.BorderFactory;
import javax.swing.JPanel;
 
 
@SuppressWarnings("serial")
public class Screen extends JPanel
implements Runnable //And Listeners later on
{
	int ScreenWidth, ScreenHeight;
 
	public Screen()
	{
		ScreenWidth=800; ScreenHeight=600;
		this.setBounds(0, 0, ScreenWidth, ScreenHeight);
		this.setBorder(BorderFactory.createTitledBorder("Game"));
 
		//Load Stuff...
 
		Thread thread = new Thread(this);
		thread.start();
	}
 
	public void run()
	{
		boolean isRunning = true;
 
		while(isRunning)
		{
			//Update Character positions
 
			//repaint()
			try
			{
				Thread.sleep(10);
			} catch (InterruptedException e){}
		}
	}
 
	public void paintComponent(Graphics g)
	{
		Graphics2D g2 = (Graphics2D)g;
		g2.setColor(Color.white);
		g2.fill(new Rectangle(0, 0, ScreenWidth, ScreenHeight));
		//painting will be done here...
	}
 
}

Looks solid to me. Good luck!
