How would I use GSON to iterate over the elements in this JSON Object to easily parse each element one by one?


Yes there is, but PrabhakarP is right, associative arrays in JSON are objects. So in your case,

{
  "Object1": {
    "description": "An object",
    "data": "more data"
  }
}

You would have a meta-object containing each array element as a property, which doesn't really make sense. You should parse it differently.

But if you still need, in GSON, then try ,

 JsonArray body = gson.fromJson(yourString, JsonArray.class);
        JSONObject metaObj = new JSONObject();  

        for (JsonElement currEle : paymentsArray) {
            JSONObject currObj = currEle.getAsJsonObject();
            String nameVal = currObj.get("name");
            currObj.remove("name");
            metaObj.addProperty(nameVal, currObj);
        }

JSON Arrays, In JSON, array values must be of type string, number, object, array, boolean or null.

JsonObject obj = gson.fromJson(jsonFile, JsonObject.class);
for(Map.Entry<String, JsonElement> element : obj.entrySet()) {
    Object obj = gson.fromJson(element.getValue(), Object.class);
    // do stuff with the object
}

jQuery.each(), Other objects are iterated via their named properties. In the case of an array, the callback is passed an array index and a corresponding array value each time.

First called array map() method is call a function for every element during iteration and return a new array for each element. This new array contains index=0 as id: “1” and index=1 as name: “kiran” Create an Object with this values in map chain to return new array Next step deep copy the array of object to new object.


JSONArray \ Language (API) \ Processing 3+, setString("name", names[i]); values.setJSONObject(i, animal); } saveJSONArray(​values, "data/new.json"); } // Sketch saves the following to a file  I know that these two classes JSONArray and JSONObject are incompatible, but still I want to do quite a natural thing - I want to for-each over JSONArray parsing at each iteration step one JSONObject (nested inside that JSONArray). I try to do it like so:


Question: How can I transform the properties of a JSON object to key , If these were delivered as an array of name/value, it would be a simple matter to map them to a PartProperties table in SQL.
