Android JSONArrays inside JSONArray

Question

Here is the relevant part of my json file:

"categories": [
     [
         "Belgian Restaurant", 
         "belgian"
     ], 
     [
         "Brasserie", 
         "brasseries"
     ]
 ], 

What I want to do is get information from the second JSONArray(say, for example, "brasseries").

The following code worked to extract information from the first array:

JSONArray categories = jsonObject.getJSONArray("categories");
restaurant.setCat1(categories.getJSONArray(0).getString(1));

The result of this was “Belgian”, as expected, but then I tried the same for the second array:

restaurant.setCat2(categories.getJSONArray(1).getString(1));

and what Index 1 out of range [0..1)JSONException chose

I do not get it, since indexes 0 and 1 explicitly exist in the file ... Why does 0 work, not 1?

Answer 1

restaurant.setCat2(categories.getJSONArray(0).getString(1));
