getInputStream错误

[Dision LI]

 public String executeGet() throws Exception {
        String httpUrl = "http://www.baidu.com/";
        String resultData = "";
        URL url = null;
        try{
            url = new URL(httpUrl);// 构造一个URL对象
        }catch (MalformedURLException e){
        }
        if (url != null){
            try{
                HttpURLConnection urlConn = (HttpURLConnection) url.openConnection();// 使用HttpURLConnection打开连接
                InputStream inputStream = urlConn.getInputStream();
                InputStreamReader in = new InputStreamReader(inputStream);// 得到读取的内容(流)
                BufferedReader buffer = new BufferedReader(in);// 为输出创建BufferedReader
                String inputLine = null;
                while (((inputLine = buffer.readLine()) != null)){// 使用循环来读取获得的数据
                    resultData += inputLine + "\n";// 我们在每一行后面加上一个"\n"来换行
                }
                in.close();// 关闭InputStreamReader
                urlConn.disconnect();// 关闭http连接
                if (resultData != null){
                    System.out.print(resultData);
                   // mTextView.setText(resultData);// 设置显示取得的内容
                }else{
                   // mTextView.setText("读取的内容为NULL");
                    System.out.print("读取的内容为NULL");
                }
            }catch (IOException e){
              //  Log.e(DEBUG_TAG, "IOException");
            }
        }else{
           // Log.e(DEBUG_TAG, "Url NULL");
        }
        return resultData;
    }

为什么在 InputStream inputStream = urlConn.getInputStream();这句错误了？

解决，internet要大写
