Question Bank Management System

Project Overview

The Question Bank Management System is a Java-based application designed to help teachers create quizzes for various modules and allow students to take these quizzes and view their results. This project demonstrates a comprehensive application of object-oriented programming principles, including inheritance, encapsulation, and polymorphism. The system handles operations such as adding, removing, and listing questions, as well as taking and evaluating quizzes.

Features

• Question Class Hierarchy: Utilizes inheritance to create a base FillTypeQuestion class and extends it to ChooseTypeQuestion and MatchTypeQuestion classes.
• Module and Bank Management: Efficient storage and retrieval of questions within modules using ArrayList.
• Custom Methods: Implementation of specialized methods for data persistence and representation.
• Exception Handling: Robust error handling to manage user inputs.
• Testing and Validation: Extensive testing to ensure all functionalities work as expected, covering a variety of test cases.

Application.java

Manages the main logic and user interaction of the application.

Bank.java

Manages collections of questions within a module.

ChooseTypeQuestion.java

Extends FillTypeQuestion to handle multiple choice questions.

FillTypeQuestion.java

Base class for all question types.

MatchTypeQuestion.java

Extends FillTypeQuestion to handle matching questions.

Module.java

Represents a module containing multiple question banks.

Person.java

Represents a user with a role in the system.

Role.java

Enumerates different roles users can have within the system.

Key Highlights

Object-Oriented Design

• Inheritance: Abstract class FillTypeQuestion is inherited by ChooseTypeQuestion and MatchTypeQuestion, demonstrating code reuse and polymorphism.
• Encapsulation: Private variables with public getter and setter methods ensure data hiding and encapsulation.

Data Structures

• ArrayList Usage: Efficient management of questions and modules using dynamic arrays.

Exception Handling

• Robust Input Validation: Ensures that the application handles incorrect inputs gracefully, maintaining the integrity of the program.

Installation

To run this project, you need to have Java installed on your system. Clone the repository and compile the Java files:

git clone https://github.com/yourusername/question-bank-management-system.git
cd question-bank-management-system/src
javac *.java

Run the application:

java Application

Usage

The Question Bank Management System allows you to:

• Add a Question: Add new questions to a bank with specific attributes.
• Remove a Question: Remove questions from a bank based on their unique ID.
• List Questions: Display a list of all questions within a bank.
• Take a Quiz: Students can take quizzes and view their results.

Testing

Extensive testing was conducted to ensure the reliability and accuracy of the system. Key test cases include:

• Adding multiple questions and ensuring they are correctly stored.
• Removing questions and verifying the integrity of the remaining list.
• Handling erroneous inputs gracefully and maintaining program stability.
