Need some help pls

Trying to write a for loop what am I doing wrong

CodeChallenge.java 
JSONArray jsonShows = jsonData.getJSONArray("jsonShows");

for (int i = 0; i < data.length(); i++){
     JSONObject = data.getJSONObject(i);
     Show show = new Show();
     show.setTitle(jsonShows.getJSONObject("title"));
     show.setSeason(jsonShows.getJSONObject("season"));
     show.setEpisode(jsonShows.getJSONObject("title"));
       Log.i(TAG, "CodeChallenge:");
}








// JSONObject 'jsonData' was loaded from data.jso
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
        }
    ]
}

In the first line of your for loop, you have not created a name for the variable to hold the JSON object.

I think you meant to have: JSONObject jsonShows= data.getJSONObject(i);

Sorry, I had to go back and actually look at the question you were referring to.

JSONArray jsonShows = jsonData.getJSONArray("shows");

for (int i = 0; i < jsonShows.length(); i++) {
  JSONObject object = jsonShows.getJSONObject(i);
  Log.i("CodeChallenge", object.getString("title"));

}

jsonShows is the array that you want to loop through... so that is the object you want to check the length of to define the for loop. You are creating an object of the Show class (or at least are trying to), but you don't have one defined (not that you need it for this question).

The "CodeChallenge" is the TAG that you want to use, and for the second parameter of the Log.i method, you want the title of the show.

Does that make sense?

Is there a section of the code I posted here that does not make sense?
