Ticket Booking System - LLD Basics - Core Java Implementation

This project is a Low-Level Design (LLD) implementation of a Ticket Booking System Entities and Services using Core Java. The system simulates a train ticket booking application and utilizes various Java 8 features such as Streams, Lambda functions, Maps, etc. The backend uses a simple JSON file-based offline database (similar to MongoDB) to store user and ticket data.

Features

The system provides the following features:

1. Sign Up - User can create an account by providing a name and password.
2. Login - Existing users can log in using their credentials.
3. Fetch Bookings - Users can view their existing bookings.
4. Search Trains - Users can search for trains based on source and destination.
5. Book a Seat - Users can book a seat on an available train.
6. Cancel Booking - Users can cancel their existing booking.
7. Exit - Exit the application.

Technologies Used

• Core Java (Java 8)
  • Streams
  • Lambda Functions
  • Maps
  • Collections (Lists, Sets, Maps, etc.)
• JSON for Offline Database (stored in .json files)
• Jackson & TypeReference for JSON parsing and to map json data with entities and object serialization/deserialization

Setup and Installation

1. Clone the repository:

git clone https://github.com/Jainish-Prajapati/IRCTC-Ticket-Booking-System-LLD-Basics-Java-8.git

2. Build the project:

gradle build

3. Run the project:

gradle run
