Why does the question require Log.i()?

This question makes no sense. Log.i is used to document errors. What is its place in this question about array management?

CodeChallenge.java
// JSONObject 'jsonData' was loaded from data.json
JSONArray jsonShows = jsonData.getJSONArray("shows");
for (int i=0; i<shows.length; i++) {
  JSONObject oneshow = shows.getJSONObject(i);
}
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 this case we're just logging the contents of the JSON for informational purposes. If we wanted to log an error we could use the Log.e function. Here's a link to the documentation on Log showing all the different log levels we can use.
