How to Efficiently Extract Actor Names from a Nested JSON Array in Android?

Parsing JSONArrays in Android

Parsing JSON data, particularly arrays within JSON objects, can present challenges, especially when starting out. Take this example:

{
    "abridged_cast": [
        {
            "name": "Jeff Bridges",
            "id": "162655890",
            "characters": [
                "Jack Prescott"
            ]
        },
        // ...
    ]
}

Objective: Extract the names of all actors in the "abridged_cast" array.

Original Code Pitfall:

The following code retrieves the "characters" array instead of the "name" property:

JSONObject jsonResponse = new JSONObject(JSON);
JSONArray movies = jsonResponse.getJSONArray("characters");

Correct Approach:

To access the "name" property, you need to iterate over the "abridged_cast" array and extract the "name" value from each actor:

List<String> allNames = new ArrayList<>();

JSONArray cast = jsonResponse.getJSONArray("abridged_cast");
for (int i = 0; i < cast.length(); i++) {
    JSONObject actor = cast.getJSONObject(i);
    String name = actor.getString("name");
    allNames.add(name);
}

Expected Output:

[Jeff Bridges, Charles Grodin, Jessica Lange, John Randolph, Rene Auberjonois]

Remember, when parsing JSONArrays, it's crucial to understand the structure of the data and iterate over the array to retrieve the specific details you need.
