If you need the result written in Java then please add an appropriate tag. You could also add the code that you already have. — Aleksandr Ivanov, Jul 25 '19 at 21:57

I suggest using Google's gson for serialization from/to json. You can find the latest version of gson here

First add this dependency to your pom.xml

Then, create in your implementation create a new Gson object:

Gson gson = new Gson();

Lets assume that you created the User model and a Users class which encapsulates User list, what you will do is:

List<User> users = gson.fromJson(responseString, Users.class);

After this point you can convert your Users object to any data structure you desire using Java streams.

You can do the vice versa by using toJson method of Gson.
