JFrame help

[Etimer]

whenever i run this, it either opens with a white screen or it opens with the stuff behind it on the screen, and whenever i minimize it and unminimize it, the screen is black.
any suggestions?

package firstgame;

import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JFrame;

public class Game extends JFrame{
	
	private static final Color BLUE = null;

	public Game(){
		
		setTitle("First Game");
		setBackground(BLUE);
		setSize(640,480);
		setResizable(false);
		setVisible(true);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	}

	public static void main(String[] args){
		new Game();
	}
	
	public void paint(Graphics g){
	g.drawString("hello", 5, 40);
	}
	
}

Read the API documentation for the JFrame class: unlike a Frame, you can't draw on a JFrame; you draw on its ContentPane instead. You can supply your own ContentPane (usually a JPanel) and draw on it.

Ok thanks! I found the api documentation, and am reading it now!

Good; it's almost lik a mantra: first read the API documentation and understand it and only then start designing and coding.

kind regards,

There's also a very god tutorial for Swing: Trail: Creating a GUI With JFC/Swing (The Java™ Tutorials)

The part you'll need to go through right away is Performing Custom Painting.
