- [Narrator] Okay, let's go straight to…the book service class and refactor the way we deserialize…the list of books we receive from the back end.…As you can see, the way we are handling this at the moment…is to specify that we want a list of books,…and that the response should attempt deserialize…this JSON into a list of books.…So let's change this, so we can do this operation manually.…So the first thing we need to do is to clear…the cached book array to ensure that the list…of books that we're going to be retrieving…is a fresh list of books.…
So what we need to do, is we need to request…that the response is deserialized to a Json array class.…We know this is the right type…because the response will be a list of books.…So we start by writing JsonArray, which we know is going…to be the type, and going to call this jsonArray.…And as before, I'm simply going to use the response.…Now, from the response, I'm going to call…the read entity entity method,…and parse into the read entity method, the JsonArray class.…
