How to Extract and Concatenate Actor Names from a JSONArray in Android?

How to Parse a JSONArray in Android

Question:

The provided JSON contains an array called "abridged_cast," and the goal is to extract the "name" field from each object in the array, concatenating them into a single String.

Answer:

The incorrect code snippet attempted to access the "characters" array, while the desired data is in the "name" field. To resolve this, use the following steps:

1. Instantiate an empty ArrayList to store the collected names.
2. Obtain the "abridged_cast" JSONArray from the JSON response.
3. Iterate over the JSONArray.
4. For each object in the array, extract the "name" field.
5. Add the "name" value to the ArrayList.

Here's an example implementation:

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);
}

String namesConcatenated = String.join(",", allNames);

This code will populate the namesConcatenated String with the names of all actors in the "abridged_cast" array, separated by commas.
