Question

How to check whether an element is a JSONArray or JSONObject. I wrote the code to check,

if(jsonObject.getJSONObject("Category").getClass().isArray()) {

} else {

}

In this case if the element ‘category’ is JSONObject then it work fine but if it contains an array then it throw exception: JSONArray cannot be converted to JSONObject. Please help.
Thanks.

Answer 1

Yes, this is because the getJSONObject("category") will try to convert that String to a JSONObject what which will throw a JSONException. You should do the following:

Check if that object is a JSONObject by using:

   JSONObject category=jsonObject.optJSONObject("Category");

which will return a JSONObject or null if the category object is not a json object.
Then you do the following:

   JSONArray categories;
   if(category == null)
        categories=jsonObject.optJSONArray("Category");

which will return your JSONArray or null if it is not a valid JSONArray .
