java如何实现播放mp3

简单的实例，代码如下，纯粹JMF加载MP3并播放：

import javax.media.*;

import java.io.IOException;

import java.util.ArrayList;

import java.util.List;

public class PlayerMusic implements ControllerListener {// ControllerListener

// 控制事件

private Player player;

private boolean first, loop;

private String path;

private List mp3List;

private int mp3NO = 0;

PlayerMusic(List mp3List) {

this.mp3List = mp3List;

}

public void start() {

try {

player = Manager.createPlayer(new MediaLocator("file://" + mp3List.get(mp3NO)));

} catch (NoPlayerException ex) {

ex.printStackTrace();

System.out.println("不能播放文件");

return;

} catch (IOException ex) {

ex.printStackTrace();

return;

}

if (player == null) {

System.out.println("播放器为空");

return;

}

first = false;

player.addControllerListener(this);

// 提取媒体内容

player.prefetch();

}

public void controllerUpdate(ControllerEvent e) {

// 当媒体播放结束时,循环播放

if (e instanceof EndOfMediaEvent) {

mp3NO++;

if(mp3NOthis.mp3List.size()){

this.start();

}

return;

}

// 当预提取媒体的内容结束

if (e instanceof PrefetchCompleteEvent) {

player.start();

return;

}

// 当实例化后

if (e instanceof RealizeCompleteEvent) {

// pack(); //执行pack()操作

return;

}

}

public static void main(String[] args) {

List mp3List = new ArrayList();

mp3List.add("d://a.mp3");

mp3List.add("d://b.mp3");

mp3List.add("d://c.mp3");

PlayerMusic pm = new PlayerMusic(mp3List);

pm.start();

}

}

用java做音视频播放器

我做过一个MP3的..给你看看.

jp1.add(shijian);

c.add(jp1);

playSound = new JButton(“开始播放“);

loopSound = new JButton(“循环播放“);

stopsound = new JButton(“停止播放“);

jp2 = new JPanel();

jp2.add(playSound);

jp2.add(loopSound);

jp2.add(stopsound);

c.add(jp2);

jp4 = new JPanel();

sj1 = new JLabel();

sj2 = new JLabel();

sldDiameter = new JSlider(SwingConstants.HORIZONTAL, 0, 100, 0);

sldDiameter.setMajorTickSpacing(1);

sldDiameter.setPaintTicks(true);

jp4.add(sj1);

jp4.add(sldDiameter);

jp4.add(sj2);

c.add(jp4);

vector = new Vector();

jl = new JList(mingcheng);

jl.setVisibleRowCount(5);

jl.setFixedCellHeight(40);

jl.setFixedCellWidth(265);

jl.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

c.add(new JScrollPane(jl));

tjian = new JButton(“添加“);

shanc = new JButton(“删除“);

duqu = new JButton(“读取“);

baocun = new JButto

JAVA 实现音频播放

这个程序只要写对了音乐文件的URL地址，例如：new URL("file:/C:/tmp/1/Windows Ding.wav");

就可以播放音乐，除了可以播放.wav格式的音乐，还可以播放.au格式的音乐。

另外，如果你不希望音乐循环播放，你可以去掉audio1.loop();这一语句。

import java.applet.AudioClip;

import java.net.MalformedURLException;

import java.net.URL;

import javax.swing.JFrame;

public class D extends JFrame{

D(){

setSize(200,200);

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

setVisible(true);

URL codebase=null;

try {

codebase = new URL("file:/C:/tmp/1/Windows Ding.wav");

} catch (MalformedURLException e) {

e.printStackTrace();

}

AudioClip audio1=Applet.newAudioClip(codebase);

audio1.loop();

}

public static void main(String[] args) {

new D();

}

}
