注意：只支持 wav 音频文件

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

import java.net.MalformedURLException;
import java.net.URI;
import java.util.concurrent.TimeUnit;

public class MusicPlayer {

    public static void main(String[] args) throws MalformedURLException, InterruptedException {

        String pathname = "I:\\Program Files (x86)\\MediaEditor\\AudioFiles\\音效\\动物世界\\猫.wav";

        File f = new File(pathname);

        URI uri = f.toURI();

        AudioClip audioClip = Applet.newAudioClip(uri.toURL());

        audioClip.play();

        TimeUnit.SECONDS.sleep(5);
