Parsing Data Returned in JSON Format

In this challenge: Finally, write a 'for' loop that loops through 'jsonBooks'. In each step of the loop, use 'getJSONObject(int index)' to get a JSONObject from the array. Then use the 'Log.i()' method (with "CodeChallenge" as the tag) to write the book title, a comma, a space, and the number of pages. Ex. output: 'Book title 1, 300'.

My code is: String name = jsonData.getString("name");

String publisher = jsonData.getString("publisher");

String language = jsonData.getString("language");

JSONArray jsonBooks = jsonData.getJSONArray("Books");

for (int i = 0; i<jsonBooks.length(); i++) {

JSONObject jsonBook = jsonBooks.getJSONObject(i);

String page = jsonBook.getString("page");

Log.i("CodeChallenge", name + ", " + page);

}

and it says: Bummer! Your loop should run twice and call 'getJSONObject()' each time through.

How should i improve it?
