Hotel Booking System in Java
Managing hotel reservations can be a complex and time-consuming process, but with a Hotel Booking System built in Java, the process becomes simpler, more efficient, and organized. This Java-based application is designed to handle room reservations, guest details, and manage bookings seamlessly, making it ideal for small inns, guesthouses, and boutique hotels.

Key Features 🌟
- Reserve a Room
The system allows the user to easily reserve rooms by entering guest details, selecting a room number, and providing contact information. It tracks the reservation details and stores them securely in a database. - View Reservations

The system is flexible, allowing users to update existing reservation details. Whether it’s a name change or a room switch, editing reservations is hassle-free. - Delete Reservations
Old or canceled bookings can easily be deleted from the system, ensuring that the reservation list stays up-to-date and clutter-free.

Getting Started 🚀
Here’s a simple guide to setting up the Hotel Booking System on your local machine.
Prerequisites
- Java Development Kit (JDK): Ensure you have JDK installed to compile and run the Java application.
- MySQL Database: The system requires a MySQL database to store and manage reservation data.
- MySQL Connector/J: This is necessary for Java to communicate with the MySQL database.
Step-by-Step Setup
If you’d like a Hotel Reservation System in Java without using a database, we can store the data in memory using Java’s ArrayList or other collection classes. This approach simplifies the code and allows you to manage hotel reservations without the complexity of setting up and managing a database.
Here’s a simplified version of the Hotel Booking System that uses an ArrayList to store reservations:
Code
import java.util.ArrayList;
import java.util.Scanner;
class Reservation {
private int id;
private int roomNumber;
private String guestName;
private String contactInfo;
private String checkInDate;
private String checkOutDate;
public Reservation(int id, int roomNumber, String guestName, String contactInfo, String checkInDate, String checkOutDate) {
this.id = id;
this.roomNumber = roomNumber;
this.guestName = guestName;
this.contactInfo = contactInfo;
this.checkInDate = checkInDate;
this.checkOutDate = checkOutDate;
}
// Getters and setters
public int getId() { return id; }
public int getRoomNumber() { return roomNumber; }
public String getGuestName() { return guestName; }
public void setGuestName(String guestName) { this.guestName = guestName; }
public String getContactInfo() { return contactInfo; }
public void setContactInfo(String contactInfo) { this.contactInfo = contactInfo; }
public String getCheckInDate() { return checkInDate; }
public String getCheckOutDate() { return checkOutDate; }
@Override
public String toString() {
return "Reservation ID: " + id +
", Room Number: " + roomNumber +
", Guest: " + guestName +
", Contact: " + contactInfo +
", Check-in: " + checkInDate +
", Check-out: " + checkOutDate;
}
}
public class HotelReservationSystem {
private ArrayList<Reservation> reservations;
private int nextReservationId;
public HotelReservationSystem() {
reservations = new ArrayList<>();
nextReservationId = 1;
}
// Method to add a new reservation
public void addReservation(int roomNumber, String guestName, String contactInfo, String checkInDate, String checkOutDate) {
Reservation reservation = new Reservation(nextReservationId, roomNumber, guestName, contactInfo, checkInDate, checkOutDate);
reservations.add(reservation);
nextReservationId++;
System.out.println("Reservation successfully added!");
}
// Method to view all reservations
public void viewReservations() {
if (reservations.isEmpty()) {
System.out.println("No reservations found.");
} else {
for (Reservation reservation : reservations) {
System.out.println(reservation);
}
}
}
// Method to update an existing reservation
public void updateReservation(int id, String guestName, String contactInfo) {
for (Reservation reservation : reservations) {
if (reservation.getId() == id) {
reservation.setGuestName(guestName);
reservation.setContactInfo(contactInfo);
System.out.println("Reservation successfully updated!");
return;
}
}
System.out.println("Reservation not found.");
}
// Method to delete a reservation
public void deleteReservation(int id) {
for (Reservation reservation : reservations) {
if (reservation.getId() == id) {
reservations.remove(reservation);
System.out.println("Reservation successfully deleted!");
return;
}
}
System.out.println("Reservation not found.");
}
// Main menu for interacting with the system
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
HotelReservationSystem system = new HotelReservationSystem();
while (true) {
System.out.println("\nHotel Reservation System Menu:");
System.out.println("1. Add a Reservation");
System.out.println("2. View All Reservations");
System.out.println("3. Update a Reservation");
System.out.println("4. Delete a Reservation");
System.out.println("5. Exit");
System.out.print("Enter your choice: ");
int choice = scanner.nextInt();
scanner.nextLine(); // Consume newline
switch (choice) {
case 1:
// Add a reservation
System.out.print("Enter Room Number: ");
int roomNumber = scanner.nextInt();
scanner.nextLine();
System.out.print("Enter Guest Name: ");
String guestName = scanner.nextLine();
System.out.print("Enter Contact Information: ");
String contactInfo = scanner.nextLine();
System.out.print("Enter Check-in Date (YYYY-MM-DD): ");
String checkInDate = scanner.nextLine();
System.out.print("Enter Check-out Date (YYYY-MM-DD): ");
String checkOutDate = scanner.nextLine();
system.addReservation(roomNumber, guestName, contactInfo, checkInDate, checkOutDate);
break;
case 2:
// View all reservations
system.viewReservations();
break;
case 3:
// Update a reservation
System.out.print("Enter Reservation ID to update: ");
int idToUpdate = scanner.nextInt();
scanner.nextLine();
System.out.print("Enter New Guest Name: ");
String newGuestName = scanner.nextLine();
System.out.print("Enter New Contact Information: ");
String newContactInfo = scanner.nextLine();
system.updateReservation(idToUpdate, newGuestName, newContactInfo);
break;
case 4:
// Delete a reservation
System.out.print("Enter Reservation ID to delete: ");
int idToDelete = scanner.nextInt();
system.deleteReservation(idToDelete);
break;
case 5:
// Exit
System.out.println("Exiting...");
System.exit(0);
break;
default:
System.out.println("Invalid choice. Please try again.");
}
}
}
}

Explanation of the System
- Reservation Class: Holds information about a single reservation, such as the room number, guest details, and dates.
- HotelReservationSystem Class: Contains an
ArrayListto store the reservations and provides methods to add, view, update, and delete reservations. - Main Menu: Allows users to interact with the system using a menu-driven interface to add new reservations, view all reservations, update, or delete them.
Running the Application
- Copy and paste the code into a Java file (
HotelReservationSystem.java). - Compile and run the program:
javac HotelReservationSystem.java
java HotelReservationSystemOnce the program runs, you’ll be presented with a menu where you can choose to add a reservation, view all reservations, update a reservation, or delete a reservation.
Feel free to modify and expand the project as per your requirements!
Usage 📋
After running the application, the system will prompt you with a menu to choose the operation you want to perform. The options are:
- Make a new reservation
- View all reservations
- Edit existing reservations
- Delete reservations
- Exit the system
