I have asked this question 3 times already and to the person who kept giving diagrams for this question please stop. I need help with the code itself not diagrams. So please if someone can help me develop the code further it would be much appreciated.

This is the code I have so far. This code presents 10 random questions out of 20 and allows the user to input an answer. This code also generates a report at the end showing which questions the user got right and wrong and what score they got over 10.

What I need is the rest of the requirements outlined in the brief above such as the results being saved to the students profile, allowing the management of multiple student profiles and a generation of an overall class report, an admin access where an admin user can see all the students attempts but a user can only see their own attempts, a student login to their profile before the quiz starts, the allowance of multiple attempts which are saved against their individual profile and lastly all the questions and answers to be saved to a simple text file which is read by the quiz application.

Please help me with the code i do not need diagrams and i wasnt able to refund the question asked 3 times that got answered by the same person 3 times incorrectly.

This is the code pasted below that needs to be developed further. Please help me with the code as best as you can this assignment is very important to me, i hope you can understand. Also the comments are disabled for some reason, i was able to comment under posts but i no longer can, is there a solution to this?

Introduction You have been tasked with solving a software problem which is defined in the problem statement section below. The assignment has been designed to ensure full coverage of all content delivered within the module, as such, to be successful you will need to be familiar with all lecture and lab material delivered to-date and over the next 2 weeks. This assignment is worth 50% of your overall grade. Please familiarise yourself with the marking scheme at the end of this document to understand what is required as assignment deliverables. Problem statement You are required to develop a Java based Multiple Choice Quiz application to aid students taking the module "Object Oriented Analysis & Design" review content in their module. Users will be presented with a randomly chosen set of 10 questions from a question bank and be presented with a choice of solutions. The user must then chose a correct answer and move to the next question. The application will generate a report of how well the student did after the quiz has completed. The student's result is saved to their profile. The application can manage many student profiles and can generate an overall class report. The quiz may be administrated by an admin user. An admin user has full access to all student's attempts, but a student user can only see their own attempts as such Student's must login to their profile before starting the quiz. Students are allowed have multiple attempts which are all persistently saved against their individual profile. Questions and solutions are saved in a simple text file which is read by the quiz application.
