Why is this code wrong?

String responseData = "";

try { URL treehouseUrl = new URL("http://blog.teamtreehouse.com/api/get_recent_summary/?count=20"); HttpURLConnection connection = (HttpURLConnection) treehouseUrl.openConnection(); connection.connect(); int responseCode = connection.getResponseCode();

if (responseCode == HttpURLConnection.HTTP_OK) {

    // Code to read InputStream goes here!
    InputStream inputStream = connection.getInputStream();
    Reader reader = new InputStreamReader(inputStream);
    char[] charArray = new char[connection.getContentLength()];
    reader.read(charArray);
    String responseData = new String(charArray);
}

} catch (MalformedURLException e) { Log.e(TAG, "MalformedURLException caught!", e); } catch (IOException e) { Log.e(TAG, "IOException caught!", e); }

You already declared the String variable responseData above.

Try this out:

InputStream inputStream = connection.getInputStream();
Reader reader = new InputStreamReader(inputStream);
char[] charArray = new char[connection.getContentLength()];
reader.read(charArray);
responseData = new String(charArray);
