I can't get the last code challenge to work

here's my code:

// JSONObject 'jsonData' was loaded from data.json String name = jsonData.getString("name"); String publisher = jsonData.getString("publisher"); String language = jsonData.getString("language");

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

for(int j = 0; j < 50; j++) { JSONObject jsonBook = jsonBooks.getJSONObject(j); String title = jsonBook.getString("CodeY 1, 200"); Log.i("CodeChallenge", "Book " + title);

}

The error just says, "Try again!"

Help please

Dear Javier,

I think you need to alter the loop itself and some of the code:

The "termination" expression should be "j < jsonBooks.lenght()" because you need to be sure the FOR statement will work the exact number of times you need and not '50'.

"for (int j = 0; j < jsonBooks.lenght(); j++)"

Also, the "title" variable is not right. The parameter for "getString" method is the name of the JSON field. I think it shoud be:

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

Do the same for the page number (use "getInt") and cancatenate all you need!

Try again and let us know.
