Java

package pingpong1;

import java.awt.Graphics;
import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionListener;

import javax.swing.JPanel;

public class Board extends JPanel implements MouseMotionListener, Runnable{
	
	private PlayerPong player = new PlayerPong();
	private Ball ball = new Ball();
	
	private boolean outOfBounds = false;
	
	private Thread th;
	
	
	public Board(){
		addMouseMotionListener(this);
		
	}
	
	protected void paintComponent(Graphics g){
		super.paintComponent(g);
		player.create(g);
		ball.create(g);
		
	}

	public void mouseDragged(MouseEvent e) {
		player.move(e.getY());
		repaint();
	}
	
	public void mouseMoved(MouseEvent e) {
		player.move(e.getY());
		repaint();
	}

	public void run() {
		while (!outOfBounds){
			try {
				ball.move();
				Thread.sleep(20);
				repaint();
			} catch (InterruptedException e) {
				
			}
		}
		
	}
}

I have no idea if I'm even on the path of doing it correctly. Any help would be appreciated. I'll add my other code below.

package pingpong1;

import java.awt.Graphics;

import javax.swing.JComponent;

public class Ball extends JComponent{
	
	private int x_pos;
	private int y_pos;
	
	private int x_speed=2;
	private int y_speed=2;
	
	
	protected void create(Graphics g){
		g.fillOval(x_pos, y_pos, 30, 30);
	}
	
	public void move(){
		x_pos+=x_speed;
		//y_pos+=y_speed;
	}
}

package pingpong1;


import java.awt.BasicStroke;
import java.awt.Graphics;
import java.awt.Graphics2D;

import javax.swing.JComponent;

public class PlayerPong extends JComponent{
	
	private int y_pos;
	
	public PlayerPong(){
		y_pos=50;
	}
	
	public PlayerPong(int y){
		this.y_pos = y;
	}
	
	
	public void move(int y){
		this.y_pos=y;
		
	}
	
	protected void create(Graphics g){
		Graphics2D g2 = (Graphics2D)g;
		g2.setStroke(new BasicStroke(4));
		g2.drawLine(20,y_pos,20,y_pos+30);
	}
	
}
