# Student Management System
## Overview
The Student Management System is a simple Java-based application that allows users to perform CRUD (Create, Read, Update, Delete) operations on student records stored in a MySQL database.
The application demonstrates basic database connectivity and interaction using JDBC.
## Features
Add Student: Add a new student record to the database.
View Student: Retrieve and display a student's details by their ID.
View All Students: Retrieve and display the details of all students.
Update Student: Update an existing student's name.
Delete Student: Remove a student record from the database.
## Prerequisites
Java Development Kit (JDK) 8 or higher.
MySQL Database Server.
MySQL JDBC Driver (mysql-connector-java).
## Database Setup
Ensure MySQL is running.
Create a database named project:
CREATE DATABASE project;
Create a student table in the project database:
USE project; CREATE TABLE student ( id INT PRIMARY KEY, name VARCHAR(100) );
Configure Database Connection
Open the ConnectionManager.java file.
Update the following fields with your MySQL credentials:
String url = "jdbc:mysql://localhost:3306/project"; String username = "root"; String password = "your-password";
## Classes and Working
**1. Student Fields:**
id: An integer representing the student ID.
name: A string representing the student's name.
Methods:
getId(): Returns the student's ID.
setId(int id): Sets the student's ID.
getName(): Returns the student's name.
setName(String name): Sets the student's name.
toString(): Returns a string representation of the student object.
Purpose: This class represents a student entity and encapsulates the student's details.
**2. ConnectionManager Fields:**
con: A Connection object used to interact with the MySQL database.
scanner: A Scanner object for reading user input.
Constructor:
Initializes the database connection using JDBC.
Methods:
addStudent(): Adds a new student record to the database by taking the student ID and name as input.
getStudent(): Retrieves and displays the details of a student based on the given ID.
getStudents(): Retrieves and displays the details of all students in the database.
removeStudent(): Removes a student record based on the given ID.
updateStudent(): Updates an existing student's name. If the student ID doesn't exist, it calls the addStudent() method to add a new student.
Purpose: This class manages the connection to the database and performs all CRUD operations on the student records.
**3. Main Purpose:**
This is the entry point of the application. It provides a menu-driven interface for the user to interact with the Student Management System.
Working: The Main class creates an instance of ConnectionManager and presents a menu with options to add, view, update, and delete student records. Based on the user's input, it calls the corresponding methods in the ConnectionManager class.
## Usage
Upon running the application, you'll be prompted with a menu to manage student records:
Add Student: Enter student ID and name to add a new student.
View Student: Enter a student ID to view details of a specific student.
View All Students: Display details of all students in the database.
Update Student: Enter a student ID and new name to update an existing student's details.
Delete Student: Enter a student ID to remove the student from the database.
Exit: Exit the application.
