Landon Hotel Scheduling App – Advanced Java Final Project

This repository contains my final project for D387 – Advanced Java at Western Governors University.

The application is a full-stack Spring Boot (Java backend) + Angular (frontend) hotel scheduling/reservation system, enhanced to demonstrate advanced Java concepts including:

• Multithreading for internationalization (i18n)
• Resource bundles for localization (English & French welcome messages)
• Currency formatting (USD, CAD, EUR)
• Custom time zone conversion (ET, MT, UTC)

The project also includes Docker containerization of the entire application.

Features Demonstrated

Backend (Spring Boot + Java)

• Multithreaded welcome messages: English and French messages displayed concurrently using separate threads and resource bundles
• Time zone conversion: Custom Java method to convert and display times in Eastern Time (ET), Mountain Time (MT), and UTC
• REST API serving reservation data

Frontend (Angular)

• Displays welcome messages in both English and French
• Shows reservation prices formatted in USD, CAD, and EUR (on separate lines)
• Displays live presentation time in ET, MT, and UTC

DevOps

• Dockerfile that builds a container image for the Spring Boot application
• Successfully tested running in a Docker container

How to Run Locally

Prerequisites

• Java 17
• Maven
• Docker (optional, for container run)

Steps

1. Clone the repository

   git clone https://github.com/Itsyourboy13/landon-hotel-advanced-java.git
   cd landon-hotel-advanced-java
   

2. Build and run with Maven

   mvn spring-boot:run

• Application runs on http://localhost:8080
• Frontend is served from the backend (static resources)

3. Open in browser

• Go to http://localhost:8080
• You will see:
  • Welcome messages in English and French (displayed via multithreading)
  • Reservation Prices in USD, CAD, and EUR after you have selected check in and check out dates and have submitted those
  • Live presentation time in ET, MT, and UTC

Run with Docker

The existing Dockerfile is already in the project and works perfectly!

Build and run:

# Build the JAR first (if not already built)
mvn clean package

# Build the Docker image
docker build -t landon-hotel .

# Run container
docker run -p 8080:8080 --name D387_landon_hotel landon-hotel

Then open http://localhost:8080

Skills Demonstrated

• Multithreaded programming in Java
• Internationalization and localization with resource bundles
• Time zone handling with Java's Date/Time API
• Full-stack development (Spring Boot + Angular)
• Docker containerization and deployment preparation

Academic Note

This project was completed as a graded assessment for WGU D387 – Advanced Java. The starter code was provided by the course. All modifications for multithreading, localization, currency display, time zone conversion, and Docker were implemented by me.

Why This Project?

This project showcases advanced Java concepts in a real-world context, including concurrent programming and internationalization — key skills for enterprise Java development.
