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

Parsing JSONArrays in Android

When working with complex JSON data, arrays of objects known as JSONArrays often arise. Parsing these arrays can be a common challenge, as exemplified by the following JSON snippet:

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

Problem Statement:

The goal is to extract the "name" property from each object in the "abridged_cast" JSONArray and concatenate them into a single string.

Solution:

The provided code attempts to access the "characters" array within the JSON, which is incorrect for this purpose. To retrieve the names, the following steps should be taken:

// Assuming `jsonResponse` is the JSONObject containing the JSON snippet

JSONArray abridgedCast = jsonResponse.getJSONArray("abridged_cast");

List<string> allNames = new ArrayList();
for (int i = 0; i <p>In this code:</p>
<ol>
<li>We obtain the "abridged_cast" JSONArray.</li>
<li>We iterate through each object in the JSONArray.</li>
<li>Inside the loop, we retrieve the "name" property from the current object.</li>
<li>We add the name to an ArrayList of strings.</li>
<li>Finally, we join the ArrayList elements into a comma-separated string.</li>
</ol></string>
