程序代码：

package text;
import *;
import javax.sound.sampled.*;
public class text {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        //创建一个实例
   
        AePlayWave apw = new AePlayWave("\\d:\\tank.mp3");
        apw.start();
    }
}
class AePlayWave extends Thread{
    private String filename;
    public AePlayWave(String wavfile){
        filename = wavfile;
    }
    public void run(){
        File soundFile = new File(filename);
        System.out.println(soundFile);
        AudioInputStream audioInputStream = null;
        try{
            audioInputStream =AudioSystem.getAudioInputStream(soundFile);
    }catch (Exception e) {
        // TODO: handle exception
        e.printStackTrace();
        return;
    }
    AudioFormat format = audioInputStream.getFormat();
    SourceDataLine auline = null;
    DataLine.Info info = new DataLine.Info(null, null);
    try{
        auline = (SourceDataLine) AudioSystem.getLine(info);
        auline.open(format);
    } catch(Exception e){
        e.printStackTrace();
        return ;
    }
    auline.start();
    int nBytesRead = 0;
    //这是缓冲

    byte[] abData = new byte[1024];
    try{
        while(nBytesRead != -1){
            nBytesRead = audioInputStream.read(abData, nBytesRead, nBytesRead);
                    if(nBytesRead >= 0){
                        auline.write(abData, 0, nBytesRead);
                    }
        }
        }catch (IOException e){
            e.printStackTrace();
            return ;

还是不行，老是报这种错误：
javax.sound.sampled.UnsupportedAudioFileException: could not get audio input stream from input file
at javax.sound.sampled.AudioSystem.getAudioInputStream(AudioSystem.java:1187)
at text.AePlayWave.run(text.java:26)
