Precondition:

Quick Start:
新建一个java project，项目名为Oops_JMF
在项目里面添加一个lib目录，并添加以下jar文件，全部可以在jmf-2_1_1e-windows-i586.exe里面找到
在src目录下面添加以下文件：
SimpleAudioPlayer.java
import javax.media.*;
import java.io.File;
import java.io.IOException;
import java.net.URL;
import java.net.MalformedURLException;
public class SimpleAudioPlayer
{
private Player audioPlayer = null;
public SimpleAudioPlayer(URL url) throws IOException, NoPlayerException,
CannotRealizeException
{
audioPlayer = Manager.createRealizedPlayer(url);
}
public SimpleAudioPlayer(File file) throws IOException, NoPlayerException,
CannotRealizeException
{
this(file.toURL());
}
public void play()
{
audioPlayer.start();
}
public void stop()
{
audioPlayer.stop();
audioPlayer.close();
}
}
TestCase.java
import java.io.File;
import java.io.IOException;
import javax.media.CannotRealizeException;
import javax.media.NoPlayerException;
public class TestCase
{
/**
* @param args
*/
public static void main(String[] args)
{
File audioFile = new File("demo.mp3");
try
{
SimpleAudioPlayer player = new SimpleAudioPlayer(audioFile);
System.out.println("music begin");
player.play();
System.out.println("music end");
} catch (NoPlayerException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
} catch (CannotRealizeException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
在项目根目录下面放置一个demo.mp3文件，最后整个项目变成：
右键点击项目，run as java application
设置好运行环境
成功！
发现很有趣。整个application运行完了，但是音乐还在继续。估计内部开了线程。
