This means that you cannot directly insert a JSONObject into a JSONArray object using the put method. Instead, you need to create a new JSONObject and then add it to the JSONArray using the add method. Here is an example:
JSONArray jsonArray = new JSONArray();
JSONObject jsonObject = new JSONObject();
jsonObject.put("name", "John");
jsonObject.put("age", 25);
jsonArray.add(jsonObject);
In this example, we first create a new JSONArray object. Then, we create a new JSONObject and add two key-value pairs to it using the put method. Finally, we add the JSONObject to the JSONArray using the add method.
