How to Access Dynamic JSON Keys in Nested Results?

Accessing Dynamic JSON Keys in Nested Results

In JSON data, keys can be dynamic, meaning they vary from object to object. This can pose a challenge when accessing specific values, especially in nested structures.

To handle dynamic JSON keys in a nested result, you can leverage the keys() method in the JSONObject class. This method returns an iterator that allows you to iterate over the available keys in the JSON object.

Consider the following JSON structure:

{
 "status": "OK",
 "search_result": [

            {
                "product": "abc",
                "id": "1132",
                "question_mark": {
                    "141": {
                        "count": "141",
                        "more_description": "this is abc",
                        "seq": "2"
                    },
                    "8911": {
                        "count": "8911",
                        "more_desc": "this is cup",
                        "seq": "1"
                    }
                },
                "name": "some name",
                "description": "This is some product"
            },
            {
                "product": "XYZ",
                "id": "1129",
                "question_mark": {
                    "379": {
                        "count": "379",
                        "more_desc": "this is xyz",
                        "seq": "5"
                    },
                    "845": {
                        "count": "845",
                        "more_desc": "this is table",
                        "seq": "6"
                    },
                    "12383": {
                        "count": "12383",
                        "more_desc": "Jumbo",
                        "seq": "4"
                    },
                    "257258": {
                        "count": "257258",
                        "more_desc": "large",
                        "seq": "1"
                    }
                },
                "name": "some other name",
                "description": "this is some other product"
            }
       ]
}

To access the content of the "question_mark" field for each object in the "search_result" array, you can use the following code:

for (JSONObject searchResult : searchResults) {
    JSONObject questionMark = searchResult.getJSONObject("question_mark");
    Iterator<string> keys = questionMark.keys();
    
    while (keys.hasNext()) {
        String currentDynamicKey = keys.next();
        
        // Get the value of the dynamic key
        JSONObject currentDynamicValue = questionMark.getJSONObject(currentDynamicKey);
        
        // Do something here with the value...
    }
}</string>

This code iterates over the available keys in the "question_mark" field and retrieves the value associated with each key. You can then use these values for further processing or display.
