4,611 Pointsi need help with JSONArray
Finally, write a 'for' loop that loops through jsonShows. In each step of the loop, use getJSONObject(int index) to get a JSONObject from the array. Then use the Log.i() method (with "CodeChallenge" as the tag) to write the show title.
JSONArray jsonShows = jsonData.getJSONArray("shows");
for (int i = 0 <jsonShows.length(); i++);
{
JSONObject show = jsonShows.getJSONObject(i);
String title = show.getString("title");
Log.i("CodeChallenge", title);
}
{
"name":"Netflix Playlist",
"shows":[
{
"title":"Doctor Who",
"season":8,
"episode":3
},
{
"title":"Arrow",
"season":1,
"episode":10
},
{
"title":"Portlandia",
"season":4,
"episode":5
}
]

3,311 PointsHere I fixed it for you, here is what went wrong: your for(conditional) line is wrong. Just two slight mistakes. Its suppose to look like this:
for (int i = 0; i < jsonShows.length(); i++)
yours was this:
for (int i = 0 <jsonShows.length(); i++); //<-- you forgot the 'i'. And don't put the ";" at the end of the conditional.
Here is the entire snippet fixed, I tested it in the challenge and it completed:
JSONArray jsonShows = jsonData.getJSONArray("shows");
for (int i = 0; i < jsonShows.length(); i++) {
JSONObject show = jsonShows.getJSONObject(i);
String title = show.getString("title");
Log.i("CodeChallenge", title);
}
