what is wrong with this code???

oop should run three times and call 'getJSONObject()' each time through.

I think I run 3 times...

CodeChallenge.java 
// JSONObject 'jsonData' was loaded from data.json
JSONArray jsonShows = jsonData.getJSONArray("data");
for(int i = 0; i < jsonShows.length(); i++){
  JSONObject show = jsonShows.getJSONObject(i);
  Log.i("CodeChallenge", "title = " + show.getString("title"));  
  Log.i("CodeChallenge", "season = " + String.valueOf(show.getLong("season")));
  Log.i("CodeChallenge", "episode = " + String.valueOf(show.getLong("episode")));
}
data.json 
{
    "name":"Netflix Playlist",
    "shows":[
        {
            "title":"Doctor Who",
            "season":8,
            "episode":3
        },
        {
            "title":"Arrow",
            "season":1,
            "episode":10
        },
        {
            "title":"Portlandia",
            "season":4,
            "episode":5
        }
    ]
}

Hi Shahaf,

I think there may be a problem with the tester for task 1 because it let you pass with "data" as the argument for getJSONArray() but you want the "shows" array. So you would need to change that argument to "shows"

Another issue is that you should only be logging the title in the for loop so you would need to remove the other 2 log statements that you have.

Also in general, challenges are generally looking for exact matches when any kind of string output is involved. In this case, it's only asking you to write the title but you added some extra output with "title = ". So you would need to remove that and only write the title.
