import java.awt.*;
import java.awt.event.*;

public class PongPanel extends JPanel implements ActionListener
{
    private Paddle paddle = new Paddle();
    private PongBall ball = new PongBall(250, 200);

    public static void main(String[] args)
    {
        JFrame f = new JFrame();
        f.setSize(806, 733);
        f.add(new PongPanel());
        f.setVisible(true);
    }

    public PongPanel()
    {
        setFocusable(true);
        addKeyListener(paddle);
        ball.addPaddle(paddle);
        Timer metronome = new Timer(50, this);
        metronome.start();
    }

    public void paintComponent(Graphics g)
    {
        g.setColor(Color.blue);
        g.fillRect(0, 0, 800, 700);
