Seems like you can't iterate through JSONArray with a for each. You can loop through your JSONArray like this:

for (int i=0; i < arr.length(); i++) {
    arr.getJSONObject(i);
}

Iterating Over an Instance of org.json.JSONObject | Baeldung
May 5, 2025 - void handleJSONArray(JSONArray jsonArray) { jsonArray.iterator().forEachRemaining(element -> { handleValue(element) }); } Now, this solution is limiting because we are combining traversal with the action we want to take. A common approach to separating the two would be using the Visitor pattern. In this article, we saw a way to iterate over a JSONObject for simple name-value pairs, the problem associated with complex structures, and a traversal technique to solve it.
