GSON. How to convert json object to json array?

Question

Now I am getting this JSON from API:

{\"supplyPrice\": {
        \"CAD\": 78,
        \"CHF\": 54600.78,
        \"USD\": 20735.52
      }}

But

Answer 1

Hope this part of code to help you:

    String json = "{\"supplyPrice\": {\n" +
            "        \"CAD\": 78,\n" +
            "        \"CHF\": 54600.78,\n" +
            "        \"USD\": 20735.52\n" +
            "      }}";

    Gson gson = new Gson();
    JsonObject jsonObject = gson.fromJson(json, JsonObject.class);
    JsonObject supplyPrice = jsonObject.get("supplyPrice").getAsJsonObject();
    Type type = new TypeToken>() {
    }.getType();
    HashMap parsedJson = gson.fromJson(supplyPrice, type);
    JsonArray jsonArray = new JsonArray();
    for(String key : parsedJson.keySet()) {
        JsonObject jo = new JsonObject();
        jo.addProperty("name", key);
        jo.addProperty("value", parsedJson.get(key));
        jsonArray.add(jo);
    }
    JsonObject result = new JsonObject();
    result.add("supplyPrice", jsonArray.getAsJsonArray());
