error: cannot find symbol reader.read(charArray);

I followed the instructions line by line and even tried looking into the documentation, then looked in the forums.

I get this error on the last part of the code challenge. I have tried an uppercase Reader.read and a lowercase reader.read.

error: cannot find symbol reader.read(charArray);

here is my code

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 read = new InputStreamReader(inputStream);
    int contentLength = connection.getContentLength();
    char[] charArray = new char[contentLength];
    Reader.read(charArray);
}

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

Ah I found my problem was that I was trying a syntax like Class.read when it should have been lowercase as in the reader object I created then .read.

So if I created a Reader object named asdf:

Reader asdf = new InputStreamReader(intputStream);

Then later I would call asdf.read(charArray);

Such a simple mistake haha.

Thanks so much to you.

This code works for me: 

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);

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

In the very last part you just have to add this line to the code:

responseData = new String(charArray);
