}

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();
}

}
}
}

用的是java swing吗
所谓停止就是将线程销毁就行啊，暂停就是让线程挂起啊。呵呵
播放音乐你写的是个线程啊，只要对线程操作就行了啊。
