java实现音乐播放器

学习过java语言的你,或多或少,在某天突发奇想,想着用swing做一个音乐播放器。但是,发现很难找到,相关的java代码,或者你下载的代码有问题,或者你代码里面引入的类包找不到。为了解决自如此类的问题。在这儿,有如下的代码可以供大家参考。

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

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();
  }

 }

 
}


好了,到此结束。
