In my first gson application I avoided using additional classes to catch values mainly because I use json for config matters

despite the lack of information (even gson page), that's what I found and used:

starting from

Map jsonJavaRootObject = new Gson().fromJson("{/*whatever your mega complex object*/}", Map.class)

Each time gson sees a {}, it creates a Map (actually a gson StringMap )

Each time gson sees a '', it creates a String

Each time gson sees a number, it creates a Double

Each time gson sees a [], it creates an ArrayList

You can use this facts (combined) to your advantage

Finally this is the code that makes the thing

        Map<String, Object> javaRootMapObject = new Gson().fromJson(jsonLine, Map.class);

    System.out.println(
        (
            (Map)
            (
                (List)
                (
                    (Map)
                    (
                        javaRootMapObject.get("data")
                    )
                 ).get("translations")
            ).get(0)
        ).get("translatedText")
    );
