如何用java做一个音乐播放器?

看看其它网友的答案:

首先下载播放mp3的包,比如mp3spi1.9.4.jar。在工程中添加这个包。

播放器演示代码如下

package com.test.audio;

import java.io.File;

import java.awt.BorderLayout;

import java.awt.FileDialog;

import java.awt.Frame;

import java.awt.GridLayout;

import java.awt.Label;

import java.awt.List;

import java.awt.Menu;

import java.awt.MenuBar;

import java.awt.MenuItem;

import java.awt.MenuShortcut;

import java.awt.Panel;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import java.awt.event.KeyEvent;

import java.awt.event.MouseAdapter;

import java.awt.event.MouseEvent;

import java.awt.event.WindowAdapter;

import java.awt.event.WindowEvent;

import javax.sound.sampled.AudioFormat;

求用java编写MP3播放器

这个需要jmf的相关包,去网上下载下,给你写了个例子

public class TestPlay extends JFrame {

private Component vc, cc;

private JButton file = new JButton("file");

private Player player = null;

public TestPlay() throws HeadlessException, NoPlayerException, MalformedURLException, IOException {

this.add(file);

file.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent arg0) {

JFileChooser f = new JFileChooser();

if(f.showOpenDialog(null)==JFileChooser.CANCEL_OPTION)return;

try {

player = Manager.createPlayer(f.getSelectedFile().toURL());

player.addControllerListener(new ControllerListener() {

public void controllerUpdate(ControllerEvent arg0) {

controllerUpdateImp(arg0);

}

});

player.prefetch();

} catch (Exception e) {

System.out.println(e);

JOptionPane.showMessageDialog(null, e.getMessage());

}

}

});

}

public void controllerUpdateImp(ControllerEvent e) {

if (e instanceof EndOfMediaEvent) {

player.setMediaTime(new Time(0));

player.start();

} else if (e instanceof PrefetchCompleteEvent) {

player.start();

} else if (e instanceof RealizeCompleteEvent) {

vc = player.getVisualComponent();

if (vc != null) this.add(vc, BorderLayout.CENTER);

cc = player.getControlPanelComponent();

if (cc != null) this.add(cc, BorderLayout.SOUTH);

this.pack();

this.setResizable(false);

this.setVisible(true);

} else if (e instanceof ControllerClosedEvent) {

System.exit(0);

}

}

public static void main(String[] args) {

TestPlay t;

try {

t = new TestPlay();

t.setDefaultCloseOperation(t.EXIT_ON_CLOSE);

t.pack();

t.setLocationRelativeTo(null);

t.setVisible(true);

} catch (Exception e) {

JOptionPane.showMessageDialog(null, e.getMessage());

}

}

}

怎么用Java写一个简单的mp3播放器,用外部包

作业其实还是自己写的好。要用到JMF包啊,到网上下载一个JMF包,照着说明安装上。

以下是我写的一个很简单的播放器,只能播放mp3,mpeg,mpg,wav等简单的格式。

如何用Java来编写一个音乐播放器

首先要在环境电脑中安装下JMF环境,才能引入javax.sound.sampled.*这个包,一下是用过的代码

package TheMusic;

import java.io.*;

import javax.sound.sampled.*;

public class Music {

public static void main(String[] args) {

// TODO Auto-generated method stub

//修改你的音乐文件路径就OK了

AePlayWave apw=new AePlayWave("突然好想你.wav");

apw.start();

}

}

在程序中实例化这个类,启动线程,实例化的时候参照Test修改路径就OK播放声音的类

Java代码

public class AePlayWave extends Thread {

private String filename;

public AePlayWave(String wavfile) {

filename = wavfile;

}

public void run() {

File soundFile = new File(filename);

AudioInputStream audioInputStream = null;

try {

audioInputStream = AudioSystem.getAudioInputStream(soundFile);

} catch (Exception e1) {

e1.printStackTrace();

return;

}

AudioFormat format = audioInputStream.getFormat();

SourceDataLine auline = null;

DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);

try {

auline = (SourceDataLine) AudioSystem.getLine(info);

auline.open(format);

} catch (Exception e) {

e.printStackTrace();

return;

}

auline.start();

int nBytesRead = 0;

byte[] abData = new byte[512];

try {

while (nBytesRead != -1) {

nBytesRead = audioInputStream.read(abData, 0, abData.length);

if (nBytesRead = 0)

auline.write(abData, 0, nBytesRead);

}

} catch (IOException e) {

e.printStackTrace();

return;

} finally {

auline.drain();

auline.close();

}

}

}
