Google Gson - deserialize list object? (generic type)

Question

I want to transfer a list object via Google Gson, but I don\'t know how to deserialize generic types.

What I tried after looking at this (BalusC\'s answer):

Answer 1

Since Gson 2.8, we can create util function like

public  List getList(String jsonArray, Class clazz) {
    Type typeOfT = TypeToken.getParameterized(List.class, clazz).getType();
    return new Gson().fromJson(jsonArray, typeOfT);
}

Example using

String jsonArray = ...
List user = getList(jsonArray, User.class);
