Hotel Reservation Application

This is a Java-based Hotel Reservation System that allows users to search for available rooms, book reservations, and manage customer accounts. Administrators can manage rooms, customers, and reservations. The project is designed to showcase object-oriented programming principles, including inheritance, polymorphism, and encapsulation.

Project Design

  • Implements Object-Oriented Programming (OOP) principles, such as inheritance, polymorphism, and encapsulation.
  • Uses the Singleton pattern for managing the system's services (like CustomerService, ReservationService).
  • Validates user input with Regular Expressions (e.g., valid email format).
  • Handles date input using SimpleDateFormat and provides robust error handling with try-catch blocks.

Technologies Used

  • Java: The core programming language for building the application.
  • Java Collections: Used to manage hotel rooms, customers, and reservations.
  • Date and Calendar APIs: Used for managing check-in and check-out dates.
  • Object-Oriented Programming: Core design principles are applied throughout the project.

Setup

Prerequisites

  • Java 8+: You need a Java Development Kit (JDK) installed on your machine.
  • Git: If you want to clone the repository from GitHub.

Compile and Run

  1. Open the project in your preferred IDE (such as IntelliJ IDEA or Eclipse).
  2. Navigate to the HotelApplication class, which contains the main method.
  3. Run the HotelApplication class to start the program.
