Project Title: Subscription Management System in Java

Objective:
The goal of this project is to develop a system that helps manage user subscriptions to various service plans. It allows users to sign up, choose a subscription plan, track their subscription status, and manage payments or renewals.

Core Features:

User Management:
Users can register, log in, and manage their profile. The system may also support different roles, such as admin and regular user.

Subscription Plan Management:
Admins can create and update different subscription plans. Each plan includes details such as name, price, duration (monthly or yearly), and description.

User Subscriptions:
Users can subscribe to available plans. The system keeps track of the start date, end date, renewal status, and current active plan of each user.

Billing and Invoices:
The system can generate invoices based on subscription plans. It records the amount, issue date, and payment status for each subscription.

Notifications:
Users can receive reminders for upcoming renewals or notifications for payment confirmation or failure.

Technology Stack:

Java for core programming

Spring Boot for building RESTful APIs (optional for advanced versions)

JDBC or Hibernate for database connectivity

MySQL or PostgreSQL for data storage

Basic user interface using Java console or a simple web frontend

Use Cases:
This system is useful for businesses offering digital products or services on a subscription basis. It can also serve as a student project to demonstrate skills in object-oriented programming, database management, and backend development using Java.
