CGPA Calculator Project in Java Using JSP, Servlet and MySQL

CGPA Calculator Project in Java is a web-based application developed using Java, JSP, Servlet, and MySQL. The project is built in Eclipse IDE using Maven and follows the MVC architecture.

This CGPA Calculator or Mark Sheet Generator project can be used as a minor or major project for BCA, MCA, and other computer science students. It helps automate the process of entering student marks, calculating results, and generating mark sheets.

The project also provides a simple way for an admin or faculty member to manage students, semesters, subjects, and marks from a single application.

CGPA Calculator Project in Java – Overview

Creating mark sheets manually for a large number of students can take a lot of time and may lead to calculation mistakes.

The CGPA Calculator project automates this process. The admin can add student information, manage subjects and semesters, enter marks, and generate the final mark sheet.

The system automatically performs the required calculations based on the marks and credits configured for each subject.

The generated mark sheet can also be printed for physical records.

Objective of CGPA Calculator Project

The main objective of this project is to make the student result and mark sheet generation process simple and automatic.

Important objectives are:

Reduce manual work in preparing mark sheets.
Automatically calculate grades and CGPA.
Manage student records digitally.
Manage semesters and subjects.
Store student marks in the database.
Generate mark sheets quickly.
Reduce calculation errors.
Make student result records easier to maintain.
Provide a simple web-based interface for faculty or admin.

Java – Main programming language.
JSP – Used to create web pages.
HTML – Used for page structure.
CSS – Used for styling.
Bootstrap – Used to create a responsive interface.
JavaScript – Used for client-side validation and functionality.
Servlet – Handles server-side requests.
JDBC – Connects Java application with MySQL.
MySQL – Stores application data.
Maven – Manages project dependencies and libraries.
MVC Architecture – Separates application logic, UI, and request handling.
Apache Tomcat 8.5 – Used to deploy and run the web application.

MVC Architecture

The CGPA Calculator project follows the MVC architecture, which makes the project easier to understand and maintain.

Model

The Model handles:

Business logic
Database operations
Student data
Subject data
Marks and result information

View

The View contains the user interface created using:

JSP
HTML
CSS
Bootstrap
JavaScript

Controller

The Controller is mainly implemented using Servlets.

Servlets receive requests from the user, process them, communicate with the Model, and return the required result to the View.
