Convert JSON to Gson with type as ArrayList

If you have a GSON String which is an object collection and you want to convert it into an ArrayLis<> using the Gson library, make use of the reflection TypeToken

ArrayList<Student> stdList = new ArrayList<>();
stdList = gson.fromJson(jsonList,  new TypeToken<ArrayList<Student>>(){}.getType());
System.out.println(stdList(0).getStudentName());
System.out.println(stdList(1).getStudentName());

import com.google.gson.Gson;
    import com.google.gson.reflect.TypeToken;

    import java.util.ArrayList;

    public class JsonToGsonExample {

        public static void main(String[] args) {

            String jsonString = "{\n" +
                    "  \"studentId\": 1,\n" +
