为什么我的声音播放不了呢，代码如下

[A18767101172]

import java.applet.Applet;
import java.applet.AudioClip;

public class MyAudioPlayer{
static AudioClip shot=Applet.newAudioClip(MyAudioPlayer.class.getClassLoader().getResource("sounds/Sleep.wav"));
boolean flag = false;
public static void main(String[]args){
new MyAudioPlayer();
}
MyAudioPlayer(){
shot.play();
shot.loop();
shot.stop();
}
/*class MyThread extends Thread{

}*/
}
