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();

}

}

}

Applet我没有学过-------现在都用Swing了,AWT都很少用的。

我跑了下你的程序,你的错误在这:

sound=getAudioClip(getDocumentBase(),"test.mp3");

也就是AudioClip 对象没有创建成功!

在监听器中触发事件的时候,你首先要判断AudioClip 不为空,然后才能进行播放!

if (obj == plays) {

if (sound != null) {

sound.play();

} else {

sound = getAudioClip(getDocumentBase(), "D:\\lalala.wma");

sound.play();

}

} else if (obj == stops) {

。。。。。

这样写是对的写法

但是sound = getAudioClip(getDocumentBase(), "D:\\lalala.wma");

还是没有构建成功。所以,你构建AudioClip估计是错误的写法。

Appletde API太老了,我没有看,所以给你个Swing写的代码,你跑下看看,编译通过的。建议你不要用Applet了!

}

记得在File mufile = new File("D:\\Lovinyou.mp3"); 这地方换为你音乐的路径

跪求java 音乐播放的代码啊,完美运行的就行
