}

AND RENDER.JAVA! is here<<<<<<<<<<<<<<

package flappyBird;

import java.awt.Graphics;

import javax.swing.JPanel;

public class Renderer extends JPanel
{

private static final long serialVersionUID = 1L;

@Override
protected void paintComponent(Graphics g)
{

    super.paintComponent(g);

    FlappyBird.flappybird.repaint(g);

}

}
