	public void method3() throws Exception {
		URL urlfile = new URL("http://www.greenworm.com/ising/song02/135_158.mp3");
		//File file = new File("C:\\music\\test2.mp3");
		//URL urlfile = file.toURI().toURL();
		URLConnection con = urlfile.openConnection();
		int b = con.getContentLength();// 得到音乐文件的总长度
		BufferedInputStream bis = new BufferedInputStream(con.getInputStream());
		Bitstream bt = new Bitstream(bis);
		Header h = bt.readFrame();
		int time = (int) h.total_ms(b);
		System.out.println(time / 1000);
