## Overview

This small Java example demonstrates a hotel-services facade. HotelApp creates and calls FrontDesk, which delegates vehicle pickup, room cleaning, and cart requests to their respective services; each service prints a confirmation. The service classes implement HotelService, an otherwise empty interface. The graph reflects the shown calls and implementations; it does not infer additional hotel workflows or state.

Main entry points: [`facadePattern/FrontDesk.java`](https://github.com/joeandreroja/roja_facadepattern/blob/main/facadePattern/FrontDesk.java) (FrontDesk Facade), [`facadePattern/HotelService.java`](https://github.com/joeandreroja/roja_facadepattern/blob/main/facadePattern/HotelService.java) (HotelService), [`facadePattern/Valet.java`](https://github.com/joeandreroja/roja_facadepattern/blob/main/facadePattern/Valet.java) (Valet), [`facadePattern/HouseKeeping.java`](https://github.com/joeandreroja/roja_facadepattern/blob/main/facadePattern/HouseKeeping.java) (HouseKeeping)
