我想用java打开mp3，怎么办？

[w678678786]

Runtime.getRuntime().exec("???");

假如我要打开d:\demo\test.mp3
问号部分应该怎样写啊？谢谢各位了，呵呵

關鍵看你的mp3播放器是什么了﹐java了調用mp3播放器

[topbit]

比如用Windows Media Player：
Runtime.getRuntime().exec("mplayer.exe music.mp3");
或者用
Runtime.getRuntime().exec("start music.mp3");

说明：
这并非是在Java中播放mp3。

要在Java中播放mp3, 要用到JMF 中的包。首先要下载 JMF。
下面是《Java 2 大学教程》上的一个示例， 我不经修改就贴到这了，看一吧。
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import javax.swing.*;
import javax.media.*; //这个包就是来自JMF

public class MediaPlayerDemo extends JFrame {
private Player player;
private File file;

public MediaPlayerDemo()
{
super( "Demonstrating the Java Media Player" );

JButton openFile = new JButton( "Open file to play" );
openFile.addActionListener(
new ActionListener() {
public void actionPerformed( ActionEvent e )
{
openFile();
createPlayer();
}
}
);
getContentPane().add( openFile, BorderLayout.NORTH );

setSize( 300, 300 );
show();
}

private void openFile()
{
JFileChooser fileChooser = new JFileChooser();

fileChooser.setFileSelectionMode(
JFileChooser.FILES_ONLY );
int result = fileChooser.showOpenDialog( this );

// user clicked Cancel button on dialog
if ( result == JFileChooser.CANCEL_OPTION )
file = null;
else
file = fileChooser.getSelectedFile();
}

private void createPlayer()
{
if ( file == null )
return;

removePreviousPlayer();

try {
// create a new player and add listener
player = Manager.createPlayer( file.toURL() );
player.addControllerListener( new EventHandler() );
player.start(); // start player
}
catch ( Exception e ){
JOptionPane.showMessageDialog( this,
"Invalid file or location", "Error loading file",
JOptionPane.ERROR_MESSAGE );
}
}

private void removePreviousPlayer()
{
if ( player == null )
return;

player.close();

Component visual = player.getVisualComponent();
Component control = player.getControlPanelComponent();

Container c = getContentPane();

if ( visual != null )
c.remove( visual );

if ( control != null )
c.remove( control );
}

public static void main(String args[])
{
MediaPlayerDemo app = new MediaPlayerDemo();

app.addWindowListener(
new WindowAdapter() {
public void windowClosing( WindowEvent e )
{
System.exit(0);
}
}
);
}

// inner class to handler events from media player
private class EventHandler implements ControllerListener {
public void controllerUpdate( ControllerEvent e ) {
if ( e instanceof RealizeCompleteEvent ) {
Container c = getContentPane();

// load Visual and Control components if they exist
Component visualComponent =
player.getVisualComponent();

if ( visualComponent != null )
c.add( visualComponent, BorderLayout.CENTER );

Component controlsComponent =
player.getControlPanelComponent();

if ( controlsComponent != null )
c.add( controlsComponent, BorderLayout.SOUTH );

c.doLayout();
}
}
}
}

即不結帖﹐也沒有任何回饋﹐什么人?白白浪費大家的時間?
本來多少分對許多人無所謂?可你起碼應尊重其它人的勞動﹐吱會一聲也好啊﹗建議版主對常這么于的人刪ID,現在回JAVA版里問的有水平的貼子越來越少﹐回答有水平的貼子也越來越少﹐跟這些人大有關系!
至少應有一個黑名單的功能﹐對這些人我可以加入黑名單﹐以后不再回它們的貼
