GSON - Get JSON value from String

I'm trying to parse the JSON String "{'test': '100.00'}" and in order to get the value: 100.00 with the GSON library. My code looks like this:

String myJSONString = "{'test': '100.00'}";
JsonObject jobj = new Gson().fromJson(myJSONString, JsonObject.class);

String result = jobj.get("test").toString();

System.out.println(result);

My result looks like this: "100.00", but I would need just 100.00 without the quotes. How can this be achieved?

double result = jobj.get("test").getAsDouble();

Try

String result = jobj.get("test").getAsString();

get(String) method returns JsonElement object which you then should get the value from.
