How to Parse Dynamic JSON Keys within Nested JSON Data?

Dynamic JSON Key Parsing in Nested JSON Results

Parsing nested JSON data can present challenges when dealing with dynamic keys. Let's explore how to access the content of "question_mark" when keys like "141", "8911", etc. vary dynamically.

Using the keys() Method

To iterate over dynamic keys, we can use the keys() method of the JSONObject class. This method returns an Iterator containing the key names. We can then iterate over this iterator to obtain the dynamic key values.

Sample Code

The following revised code demonstrates how to access the content of "question_mark" dynamically:

// Assuming searchResult is the current element in the "search_result" array
JSONObject questionMark = searchResult.getJSONObject("question_mark");
Iterator<String> keys = questionMark.keys();

while (keys.hasNext()) {
    // Obtain the dynamic key
    String dynamicKey = keys.next();

    // Obtain the value for the dynamic key
    JSONObject dynamicValue = questionMark.getJSONObject(dynamicKey);

    // Perform operations on the dynamic value...
}

By iterating over the keys() iterator, we can access each dynamic key and its corresponding value. This allows us to obtain the information we need for the "question_mark" property in a dynamic manner.
