Campus Course & Records Manager (CCRM)

1. Project Brief

CCRM is a console-based Java application designed for an educational institute to manage students, courses, enrollments, and grades. It serves as a comprehensive demonstration of core Java SE features, Object-Oriented Programming (OOP) principles, modern Java APIs, and fundamental design patterns.

2. Features

• Student Management: Add, list, and view student profiles.
• Course Management: Add, list, and filter courses by department or semester.
• Enrollment & Grading: Enroll students in courses, assign grades, and compute GPA.
• Transcript Generation: Print a full academic transcript for any student.
• File Utilities:
  • Export student and course data to CSV-like files.
  • Create timestamped backups of all data files.
  • (Optional) Import data from pre-formatted CSV files.
• Robust & Modern Codebase:
  • OOP: Encapsulation, Inheritance, Abstraction, Polymorphism.
  • Design Patterns: Singleton (for services), Builder (for model creation).
  • Modern Java: NIO.2 for file I/O, Streams API for data manipulation, Date/Time API for timestamps.
  • Core Concepts: Demonstrates enums, lambdas, recursion, and comprehensive exception handling.

3. Project Structure

The project is organized into logical packages to ensure separation of concerns:

• com.ccrm.cli: Handles all command-line interface logic.
• com.ccrm.model: Contains all data entities (POJOs), enums, and abstract classes.
• com.ccrm.service: Manages business logic and data persistence (in-memory).
• com.ccrm.util: Provides utility functions, primarily for file operations.
• com.ccrm.exception: Defines custom exceptions for specific error conditions.

4. How to Compile and Run

Prerequisites

• Java Development Kit (JDK) 11 or higher.
• An IDE like IntelliJ, Eclipse, or VS Code (recommended), or just a terminal.

Steps

1. Clone the repository:

   git clone <your-repository-url>
   cd CCRM

2. Compile the code: Navigate to the src directory and run the Java compiler.

   # From the CCRM/src directory
   javac com/ccrm/Main.java -d ../bin

   (Note: Compiling manually can be complex due to packages. It's highly recommended to open the project in an IDE and run it from there.)

3. Run the application: From the bin directory that was created, run the main class.

   # From the CCRM/bin directory
   java com.ccrm.Main

Using an IDE (Recommended)

1. Open your IDE (e.g., IntelliJ IDEA).
2. Select "Open" or "Import Project" and choose the cloned CCRM directory.
3. Locate the src/com/ccrm/Main.java file.
4. Right-click on the file and select "Run 'Main.main()'".
