java 中url问题？？

Question

用这个类：HttpURLConnectionURL url = new URL("yourUrl");
HttpURLConnection httpConn =(HttpURLConnection) url.openConnection();
httpConn.setRequestMethod("POST");
httpConn.setDoOutput(true);
httpConn.getOutputStream().write(("name=yourname&age=yourage").getBytes("ISO8859-1"));
httpConn.getOutputStream().flush();
httpConn.getOutputStream().close();//以下是获得反馈
BufferedReader in = new BufferedReader(new InputStreamReader(httpConn.getInputStream()));
input = "";
while ((input = in.readLine()) != null) {
    System.out.println(input);
}
in.close();
httpConn.disconnect();yourUrl是你表单提交的url
name=yourname&age=yourage 这一串是你的参数内容
