Consider I have JSON file that contains,

(This is just a sample, the real JSON have more then 100 questions)

Using java, how to display next object or next question in "questions" array, when user inputs next into the console. (i.e.) users starts with Q1, hence console displays object of that question (topic:Science, points: 10 (etc)), but when user input next into console, then java would display objects of "Q2" (topic: maths...), and so on.

Prefer using object mapper and jackson tree to read in JSON but JSONObject and JSONArray is also as fine.
