How to Parse JSON Arrays into Java Arrays?

Parsing JSON Arrays into Java Arrays

The provided code successfully parses JSON objects and extracts their key-value pairs. However, it faces challenges when dealing with complex JSON structures like arrays within objects.

To access and convert array values into a Java array, we can utilize the getJSONArray method:

JSONObject myjson = new JSONObject(the_json);
JSONArray the_json_array = myjson.getJSONArray("profiles");

This returns an array object named the_json_array.

To iterate over the array:

int size = the_json_array.length();
ArrayList<JSONObject> arrays = new ArrayList<>();
for (int i = 0; i < size; i++) {
    JSONObject another_json_object = the_json_array.getJSONObject(i);
    arrays.add(another_json_object);
}

Finally, to convert the ArrayList into a Java array:

JSONObject[] jsons = new JSONObject[arrays.size()];
arrays.toArray(jsons);

This approach allows us to extract and manipulate JSON arrays into Java array structures for further processing.
