Did we really need to use the getJSONObject method besides just to follow the video?

Instead of writing

titles[i] = jsonVideos.getJSONObject(i).getString("title");

could we have used something like this?

titles[i] = jsonVideos.get(i).title.toString();

CodeChallenge.java 
/*** This code is an excerpt from a class that extends ListActivity ***/

JSONArray jsonVideos = jsonData.getJSONArray("videos");
String[] titles = new String[jsonVideos.length()];

// Write for loop here!
data.json
