Insufficient context. Command line? AWT? Swing? other GUI toolkit?

The question as posted doesn't even state that this is a Java program.

import java.applet.*;
import java.awt.*;

import javax.swing.*;

import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionAdapter;
import java.awt.geom.*;
import java.util.concurrent.*;

public class Pong extends JApplet
{
public static final int WIDTH = 350;
public static final int HEIGHT = 300;

private PaintSurface canvas;

public void init()
{
this.setSize(WIDTH, HEIGHT);
canvas = new PaintSurface();
this.add(canvas, BorderLayout.CENTER);

ScheduledThreadPoolExecutor executor = new ScheduledThreadPoolExecutor(3);
executor.scheduleAtFixedRate(new AnimationThread(this),
0L, 20L, TimeUnit.MILLISECONDS);
}
}

class AnimationThread implements Runnable
{
JApplet c;

public AnimationThread(JApplet c)
{
this.c = c;
}

public void run()
{
c.repaint();
}
}

class PaintSurface extends JComponent
{
int x_pos = 0;
int y_pos = 0;
int x_speed = 1;
int y_speed = 1;
int d = 20;
int width = Pong.WIDTH;
int height = Pong.HEIGHT;

public void paint(Graphics g)
{Graphics2D g2 = (Graphics2D)g;
g2.setRenderingHint(
RenderingHints.KEY_ANTIALIASING,
RenderingHints.VALUE_ANTIALIAS_ON);
if (x_pos < 0 )
{
x_speed = -x_speed;
}
if (x_pos > width - d)
{
x_speed = -x_speed;
}

if (y_pos < 0 )
{
y_speed = -y_speed;
}


x_pos += x_speed;
y_pos +=y_speed;
Shape ball = new Ellipse2D.Float(
x_pos, y_pos, d, d);
g2.setColor(Color.CYAN);
g2.fill(ball);
int d;
d = 8; //I want d to be controlled by g and h
Shape bally = new Rectangle.Float(d,250, 50, 8);
g2.setColor(Color.CYAN);
g2.fill(bally);
}}
