mouseListener and MouseMotionListener in Java

hello, for a school assignment, i have elected to do Pong, in a standard applet. to come at this, I used a thread, that implements Runnable for the main class. I also need to use MouseListener and MouseMotionListener. But i cannot implement them. How do i get around that. Below i have copied the code. Please help! It is due on friday.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.applet.*;

public class JavaPong extends Applet implements Runnable{


	String color = "WHITE";
	boolean done = false;				// done
	Point ballPosition;					//position
	double ballx, bally; 				// velocity
	int rad;							//balls size
	Rectangle player, computer, walls;	//rectangles
	Thread game;						//main executing thread
	Image doublebuffer;					//offscreen buffer

	AudioClip wavPong;					//sound effect
	boolean hit = false;				//if ball hit wall or paddle

	Image bgImage;						//background image

	boolean start;

	int yourScore,oppScore;

	Point mouse;						//Mouses Current Position

	public void run(){
		//infinate game loop
		try{
			while(!done){
				testPlayer();
				tesWalls();
				updateBall();
				updatePlayer();
				playSounds();

	//init(), then start()

	public void init(){

		rad = radIn;															//ball radius = x;
		ballx = -4.0;
