Can I get value from JSONObject without mention its name?

Question

My JSONObject:

{MyJSON:[{"id":"1","name":"panji","price":"100"}]}

I do this to get value of id:

menuitemArray.getJSONObject(i).getString("id");

Can I get the value of id, name or price, without mentioning its name, may be like index or another method?

What's wrong with mentioning the name? Are you facing issues with that? — Mat, May 05 '12 at 06:58

You can call names() on a JSONObject to get a JSONArray of the names of its elements - this would let you do logic on them or retrieve their corresponding values dynamically.

Thanks for the answer. Never knew there is a `names` method for `JSONObject` and I has been wasting hours trying to use `Iterator` – X09 Oct 19 '16 at 17:18

You can get all the attributes of a JSONObject like this

for(Iteraor key=jsonObject.keys();itr.hasNext();) {
   jsonObject.get(key.next());
}

I'm not sure that you can use an `Iterator` with the for-each syntax, as annoying as that is. AFAIK it only works with `Iterable`s and arrays. – Paul Bellora May 05 '12 at 07:05

JSONObject obj = new JSONObject(json);
for(Iterator<String> keys=obj.keys();keys.hasNext();) {
    obj.get(keys.next());
}
