Student Management System

A Java console application for managing student records through CRUD operations, search functionality, input validation, and local file persistence.

Overview

The Student Management System is a lightweight application developed using Core Java without external frameworks. It provides a menu-driven interface for creating, viewing, updating, deleting, and searching student records.

Student information is stored in a local text file, allowing records to persist between application runs.

Features

• Add Students: Create student records with unique IDs.
• View Students: Display all stored student records.
• Update Records: Modify student names and grades.
• Delete Students: Remove records using student IDs.
• Search Students: Find students by ID or name.
• Unique ID Validation: Prevent duplicate student identifiers.
• File-Based Persistence: Save and retrieve records using students.txt.
• Console Interface: Navigate the application through a simple interactive menu.

Getting Started

Prerequisites

• Java Development Kit (JDK)
• A terminal or command prompt

Verify your Java installation:

java -version
javac -version

1. Clone the repository

Replace YOUR_USERNAME with the actual GitHub username if needed.

git clone https://github.com/YOUR_USERNAME/student-management.git
cd student-management

2. Compile the application

If Main.java and its required source files are in the current directory:

javac *.java

3. Run the application

java Main

4. Use the menu

Follow the prompts to add, view, update, delete, or search for student records.

Data Persistence

Student records are stored in a local file named students.txt.

Each record follows this format:

id,name,grade

Example:

101,John Smith,15.5
102,Jane Doe,17.0

The file allows student records to be reused across application sessions, provided the application correctly loads and saves the file.

Note: Because records use a comma-separated format, names containing commas require appropriate parsing or escaping to avoid incorrect field separation.

Concepts Demonstrated

• Object-oriented programming and class design
• CRUD operations
• Java collections and record management
• File reading and writing
• Input validation and duplicate checking
• Searching and updating data
• Console-based user interaction

Potential Improvements

• Add automated unit tests for CRUD operations and validation.
• Improve error handling for missing, unreadable, or malformed data files.
• Use a more robust CSV format or a structured serialization format.
• Separate business logic, data access, and console interaction into distinct classes.
• Add a database-backed version using JDBC or Spring Boot.
