It looks like too much boilterplate to convert a json array to string[]. Is there any simpler and elegant way?

final JSONArray keyArray = input.getJSONArray("key");
String[] keyAttributes = new String[keyArray.length()];
for(int i = 0; i < keyArray.length(); i++) {
    keyAttributes[i] = keyArray.getString(i);
}

Assuming org.json.JSONArray. Nope, that's as good as it gets. –  Dean Povey Jan 24 '11 at 6:59

Use gson. It's got a much friendlier API than org.json.

Collections Examples (from the User Guide):

Gson gson = new Gson();
Collection<Integer> ints = Lists.immutableList(1,2,3,4,5);

//(Serialization)
String json = gson.toJson(ints); ==> json is [1,2,3,4,5]

//(Deserialization)
Type collectionType = new TypeToken<Collection<Integer>>(){}.getType();
Collection<Integer> ints2 = gson.fromJson(json, collectionType);
//ints2 is same as ints

Thanks. int[] ints2 = gson.fromJson("[1,2,3,4,5]", int[].class); something like this is what I was looking for. –  Fakrudeen Jan 24 '11 at 10:01

It's ugly but believe it or not this works:

String[] keyAttributes = keyArray.toString.substring(1,keyArray.toString.length-1).replaceAll("\"","").split(",")

There is no any built-in method that do this and I think it is the simplest way

Even using a 'well known' library would do for me. –  Fakrudeen Jan 24 '11 at 7:07
