🏨 The Java Hotel Management System

This project involves creating a hotel management system in Java, simulating the process of checking in and out of a hotel, provided certain requirements are met. The project helps in improving your understanding of Java syntax and object-oriented programming (OOP) concepts.

Goal

Upgrade and improve your understanding of Java syntax through practice. Apply and understand object-oriented programming concepts in Java by creating and implementing methods and manipulating objects to simulate a hotel management system.

Skills

• Create classes and define methods with Java.
• Learn how to use getters and setters to access and modify object properties.
• Practice using composition and delegation to create a hotel simulation system.
• Use constructors to initialize objects with default and custom values.
• Declare methods and use return values to perform specific tasks in your program.
• Utilize loops to iterate over arrays and manipulate array elements.
• Work with primitive and reference Java types and understand the differences between them.
• Understand how to use enums.

Instructions

The task is to create a hotel management system with Java. The system should allow one or more people to check in and out of a hotel. Below is a general outline of the requirements:

• A hotel can have rooms of type Single, Double, or Suite, all with different prices.
• A hotel has many rooms available, and these rooms can eventually be occupied.
• A hotel should be able to occupy or vacate its rooms.
• A person can only check in to a hotel they’re not already staying at.
• A person can only check in to a hotel that isn’t fully booked.
• A person can only check out of a hotel that they’re staying at.
• A person must have a way to identify themselves at this hotel (e.g., a hotel key or room number).
• A person shouldn’t be able to check out of another person’s room accidentally.
• A person must have a bank where they can keep track of their money to pay for the hotel. Financial activity should be handled by the bank, not the person directly.
• A person must have sufficient funds in the bank to pay for their stay.
• When checking in, a person must state whether they want a Single, Double, or Suite.
