Help on simple two player Pong!!

Question

I am fairly new to java. But I know quit a bit already. I want my to write a program that is just pong and has two paddles. One player controls one and the second player controls the other. Can anyone help me with it here is my code: ( I have tryed a switch statement for handling the keyboard but it doesn't work can anyone help me?)
import java.awt.*;
public class Pong extends java.applet.Applet
          int x = 245;
          int y = 145;
          int xVelocity = 3;
          int yVelocity = 3;
          int playerOneY = 105;
          int playerOneY2 = 110;
          int playerTwoY = 105;
          int playerTwoY2 = 110;
          Color ballColor = new Color(25, 120, 190);
          Color panelColor = new Color(220, 35, 70);
     public void paint(Graphics g)
               while(true)
               g.setColor(panelColor);
               g.fillRect(0,playerOneY,5,playerOneY2);
               g.fillRect(495,playerTwoY,500,playerTwoY2);     
               g.setColor(Color.lightGray);
               g.fillRect(0,305,510,310);
               g.fillRect(0,0,510,5);
               g.setColor(Color.white);
               g.fillOval(x,y,25,25);
               x += xVelocity;
               y += yVelocity;
               g.setColor(ballColor);
               g.fillOval(x,y,25,25);
               // bounces off paddles
               if((y < playerOneY) && (y > playerOneY2))
                    if(x<0)
                         xVelocity = +xVelocity;     
               if((y < playerTwoY) && (y > playerTwoY2))
                    if(x>500)
                         xVelocity = -xVelocity;
               //bounce off top walls
               if((y > 285) || (y < 25))
                    yVelocity = -yVelocity;     
               if((y < 0) || (y > 285))
                    yVelocity = +yVelocity;
               g.setColor(ballColor);
               g.fillOval(x,y,25,25);
               for(int i=0; i<20000000; i++);
               repaint();
}

Heres soem suggestions.... To to keyboard interaction, you need to import java.awt.event.*
then have your class implement KeyListener or use a KeyAdapter , then addKeyListener(this) in the constructor or else where, then implement each of the key event methods, but just use the keyPressed(KeyEvent e) method, then in that, get the key code, like this:
public void keyPressed(KeyEvent e)
        int key = e.getKeyCode() //gets the code of the key pressed
         switch(key)
                 case KeyEvent.VK_LEFT: blahblah();  break;
}
