这是桨类：

public class Paddle implements Runnable {

this.x = x;
this.y = y;
this.id = id;
paddle = new Rectangle(x, y, 10, 50);
}
public void keyPressed(KeyEvent e){
switch(id){
default:
System.out.println("Please enter a valid ID in Paddle constructor");
break;
case 1:
if(e.getKeyCode() == e.VK_W){
setYDirection(-1);

这是我制作的声音类：
package ponggame;
import java.applet.Applet;
import java.applet.AudioClip;
public class Sound {
public static final Sound bgMusic = new Sound("/pong.wav");
public static final Sound hitPaddle = new Sound("/bounce.wav");
private AudioClip clip;
public Sound(String fileName) {
try {
// gets the sound file that is passed in the constructor
clip = Applet.newAudioClip(Sound.class.getResource(fileName));
} catch (Exception e) {
e.printStackTrace();
}
}
// plays the music, obviously
public void play() {
try {
new Thread() { //multi-tasking stuff
public void run(){
//clip.play();
clip.loop();
}
}.start();
} catch (Exception e) {
e.printStackTrace();
}
}
//plays the audio in a loop
public void loop(){
play();
}
}
