在 applet 中播放声音文件非常简单,一般需要以下步骤:创建一个 AudioClip 对象

装入 .au 声音文件到 AudioClip 对象
一次播放或者不停循环播放声音
停止播放
下面是相应的代码:import java.applet.*;AudioClip ac = getAudioClip(getCodeBase(), soundFile);
ac.play(); //play once
ac.stop(); //stop playing
解决这个问题的窍门是利用由 Sun 及 其JDK 提供的某些 undocumented 的特征。先看看 Sun JDK 中的文件 classes.zip (使用任何解压工具即可),发现其中不仅包含标准的 Java 包如 java.applet 而且还存在包 sun.audio. (在 sun/audio 的目录下.)
包 sun.audio 中包含了用于播放声音文件所需的所有东西!下面是示例代码:import sun.audio.*; //import the sun.audio package
import java.io.*;//** add this into your application code as appropriate// Open an input stream to the audio file.
InputStream in = new FileInputStream(Filename);// Create an AudioStream object from the input stream.
AudioStream as = new AudioStream(in);// Use the static class member "player" from class AudioPlayer to play
// clip.
AudioPlayer.player.start(as);// Similarly, to stop the audio.
AudioPlayer.player.stop(as);如果要用一个 URL 做为声音流的源(source),则用下面的代码所示替换输入流来创建声音流:AudioStream as = new AudioStream (url.openStream());如果需要持续播放声音文件,则要稍稍复杂一点:// Create audio stream as discussed previously.
// Create AudioData source.
AudioData data = as.getData();// Create ContinuousAudioDataStream.
ContinuousAudioDataStream cas = new ContinuousAudioDataStream (data);// Play audio.
可以通过Service来播放背景音乐,以下是实现代码:
1.在AndroidManifest.xml文件中的application标签内加入下边语句
service android:name=".MusicServer"
intent-filter
action android:name="com.angel.Android.MUSIC"/
category android:name="android.intent.category.default" /
/intent-filter
/service
2.新建MusicServer.java类,内容为
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
public class MusicServer extends Service {
private MediaPlayer mediaPlayer;
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onStart(Intent intent,int startId){
super.onStart(intent, startId);
if(mediaPlayer==null){
// R.raw.mmp是资源文件,MP3格式的
mediaPlayer = MediaPlayer.create(this, R.raw.abc);
mediaPlayer.setLooping(true);
mediaPlayer.start();
}
}
@Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
mediaPlayer.stop();
}
}
3.将歌曲放入raw文件夹下,名称为abc。
4.在Activity中加入代码
private Intent intent = new Intent("com.angel.Android.MUSIC");
onCreate方法中加入startService(intent);
就可以播放了。

不知道你是在java里哪添加?Swing界面中吗?
下面这个是我之前做Swing界面程序时添加音乐的代码,希望对你有帮助
AudioClip[] musics;//定义音乐集合
musics = new AudioClip[2];//初始化
URL url1 = this.getClass().getResource("/ReadyGo.WAV"); //定义音乐文件地址
URL url2 = this.getClass().getResource("/back1.mid"); //定义音乐文件地址
musics[0] = JApplet.newAudioClip(url1);
musics[1] = JApplet.newAudioClip(url2);
musics[0].play();//音乐开始执行
musics[1].stop();//停止播放
java中打开音乐播放器的方式是使用audioclip类来播放音乐,实例如下:
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import javax.swing.*;
import java.io.File;
class AudioPlayDemo extends JFrame implements ActionListener {
boolean looping = false;
File file1 = new File("music\\明天会更好.wav");
AudioClip sound1;
AudioClip chosenClip;
JButton playButton = new JButton("播放");
JButton loopButton = new JButton("循环播放");
JButton stopButton = new JButton("停止");
JLabel status = new JLabel("选择播放文件");
JPanel controlPanel = new JPanel();
Container container = getContentPane();
public AudioPlayDemo() {
try {
sound1 = Applet.newAudioClip(file1.toURL());
chosenClip = sound1;
} catch(OutOfMemoryError e){
System.out.println("内存溢出");
e.printStackTrace();
} catch(Exception e){
e.printStackTrace();
}
playButton.addActionListener(this);
loopButton.addActionListener(this);
stopButton.addActionListener(this);
stopButton.setEnabled(false);
controlPanel.add(playButton);
controlPanel.add(loopButton);
controlPanel.add(stopButton);
container.add(controlPanel, BorderLayout.CENTER);
container.add(status, BorderLayout.SOUTH);
setSize(300, 130);
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //关闭窗口时退出程序
}
public void actionPerformed(ActionEvent event) {
if (chosenClip == null) {
status.setText("声音未载入");
return;
}
Object source = event.getSource(); //获取用户洗涤激活的按钮
if (source == playButton) {
stopButton.setEnabled(true);
loopButton.setEnabled(true);
chosenClip.play();
status.setText("正在播放");
}
if (source == loopButton) {
looping = true;
chosenClip.loop();
loopButton.setEnabled(false);
stopButton.setEnabled(true);
status.setText("正在循环播放");
}
if (source == stopButton) {
if (looping) {
looping = false;
chosenClip.stop();
loopButton.setEnabled(true);
} else {
chosenClip.stop();
}
stopButton.setEnabled(false);
status.setText("停止播放");
}
}
public static void main(String s[]) {
new AudioPlayDemo();
}
}
只能播放wav格式的歌曲
