InputStream输入流，读取数据实例

读取网络数据，是输入流，用InputStream

实例：

public static void getNewsJSON(final String url,final Handler handler){        new Thread(new Runnable() {            @Override            public void run() {                HttpsURLConnection connection;                InputStream isInputStream;                try {                    **connection = (HttpsURLConnection) new URL(url).openConnection();                    connection.setRequestMethod("GET");                    isInputStream = connection.getInputStream();//获取网络连接的输入流，用于读取                    BufferedReader reader = new BufferedReader(new InputStreamReader(isInputStream));**                    String lineString = "";                    StringBuilder resultBuilder = new StringBuilder();//不能为null                    while((lineString = reader.readLine()) != null){                        resultBuilder.append(lineString);                    }                    Message message = new Message();                    message.obj = resultBuilder;                    handler.sendMessage(message);                } catch (MalformedURLException e) {                    e.printStackTrace();                } catch (IOException e) {                    // TODO Auto-generated catch block                    e.printStackTrace();                }            }        }).start();    }
