Campus Course & Records Manager (CCRM)

Project Overview

This is my Java SE console project named Campus Course & Records Manager (CCRM).
It is a menu-driven program where an institute can manage:

• Students (add, update, list, enroll, transcripts)
• Courses (create, update, assign instructors, search/filter)
• Enrollment & Grades (record marks, calculate GPA, print transcript)
• File utilities (import/export CSV, create backup folders, recursive folder size)

I tried to cover all important concepts from the syllabus like OOP, Exception Handling, Streams, NIO.2, Date/Time API, Singleton and Builder patterns etc. The project is written completely in Java without any external frameworks.

How to Run

Requirements

• JDK 17 (or higher) installed
• Any IDE (I used Eclipse), or you can run from terminal
• Git (if you want to clone repo)

Steps (Eclipse)

1. Open Eclipse → File → Import → Existing Project
2. Browse this repo folder and finish
3. Right click MainApp (inside edu.ccrm.cli) → Run As → Java Application

Steps (Terminal)

# Compile
find src -name "*.java" > sources.txt
javac -d bin @sources.txt

# Run (main class may vary, in my case:)
java -cp bin edu.ccrm.cli.MainApp


Demo Workflow

When you run the project, you will see a text menu.
Suggested flow to test:

Add a new Student

Add a Course

Enroll student into the course

Record grades and generate transcript

Export data into exports/ folder

Run Backup option → creates new timestamped folder in backups/

Use recursive utility to check backup folder size

Screenshots of all these steps are kept in /screenshots

JDK vs JRE vs JVM

JDK = compiler + dev tools + JRE

JRE = libraries + JVM (to run Java)

JVM = runs bytecode, platform independent
