中央天气预报Api返回的Json乱码问题，求指教。

public class test {
	public static void main(String[] args) {
		try {
			URL url = new URL("http://m.weather.com.cn/data/101010100.html");
			InputStream inputstream = url.openStream();
			String s, str = "";
			BufferedReader in = new BufferedReader(new InputStreamReader(
					inputstream));

			Writer out = new BufferedWriter(new OutputStreamWriter(
					new FileOutputStream("d:/weather.xml"), "utf-8"));
			while ((s = in.readLine()) != null) {
				str += s;
				System.out.println(str);
			}
			out.write(str);
			out.close();
			in.close();
		} catch (MalformedURLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (UnsupportedEncodingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

}

打印出来 乱码了
{"weatherinfo":{"city":"鍖椾含","city_en":"beijing","date_y":"2014骞?鏈?鏃?,"date":"","week":"鏄熸湡浜?,"fchh":"11","cityid":"101010100","temp1":"8鈩儈-3鈩?,"temp2":"8鈩儈-3鈩?,"


求指教！！
------解决方案--------------------
BufferedReader in = new BufferedReader(new InputStreamReader(
                    inputstream));

改成

BufferedReader in = new BufferedReader(new InputStreamReader(
                    inputstream,"UTF-8"));

即可
