I am creating a Java 2D video game. I can load graphics just fine, but when it gets into double buffering I have issues.

My source code

package myPackage;

import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Image;
import java.awt.Toolkit;
import java.awt.image.BufferStrategy;
import java.awt.image.BufferedImage;

import javax.swing.JFrame;

public class GameView extends JFrame {

    private BufferedImage backbuffer;
    private Graphics2D g2d;

    public GameView() {

        setBounds(0, 0, 500, 500);
        setVisible(true);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        backbuffer = new BufferedImage(getHeight(), getWidth(),
                BufferedImage.TYPE_INT_BGR);
        g2d = backbuffer.createGraphics();

        Toolkit tk = Toolkit.getDefaultToolkit();
        Image img = tk.getImage(this.getClass().getResource("cage.png"));
        g2d.setColor(Color.red);
        //g2d.drawString("Hello",100,100);
        g2d.drawImage(img, 100, 100, this);
        repaint();
    }

    public static void main(String args[]) {
        new GameView();
    }

    public void paint(Graphics g) {
        g2d = (Graphics2D)g;
        g2d.drawImage(backbuffer, 0, 0, this);
    }

}
