Convert json array to a java list object [duplicate]

Answer 1

You need to use a supertype token for the unmarshalling, so that Gson knows what the generic type in your list is. Try this:

TypeToken<List<Person>> token = new TypeToken<List<Person>>(){};
List<Person> personList = gson.fromJson(response, token.getType());

And iterate through the results as such:

for(Person person : personList) {
    // some code here
}
