Software Engineering HW4 - #7, 8, 9

This project demonstrates three design patterns implemented in Java: Observer Pattern, Factory Method Pattern, and Adapter Pattern. Each pattern is implemented in separate classes with a Main file to demonstrate the functionality.

Prerequisites

  • Java 17 or later: Ensure you have Java Development Kit (JDK) version 17 or above installed.
  • Maven 3.x or later: The project uses Maven for dependency management and build automation.

Project Structure

Classes

  • CarFactory: Factory class for creating different types of cars
  • LegacyReservation: Legacy reservation system class
  • LuxuryCar: Implementation of luxury car type
  • Main: Main class to demonstrate pattern usage
  • Mediator: Interface for mediator pattern
  • MessageMediator: Implementation of message mediator
  • NormalCar: Implementation of standard car type
  • Observer: Interface for observer pattern
  • ReservationAdapter: Adapter for reservation system
  • ReservationSystem: Interface for reservation system
  • Rider: Class representing a rider
  • RiderObserver: Implementation of rider observer
  • ShareableCar: Interface for shareable cars
  • SUVCar: Implementation of SUV car type
  • WheelchairAccessibleCar: Implementation of wheelchair accessible car type

Test Folder

Includes the following test classes:

  • RiderMediatorTest.java: Tests the Observer Pattern implementation
  • CarFactoryTest.java: Tests the Factory Method Pattern implementation
  • ReservationAdapterTest.java: Tests the Adapter Pattern implementation

Build and Run Instructions

Clone the Repository

git clone https://github.com/naim1115/SoftwareEngineeringHW4.git

cd SoftwareEngineeringHW4

Build the Project

Use Maven to compile the project:

mvn clean install

Run the Code

Execute the Main class to see the demonstration of all three patterns:

mvn exec:java -Dexec.mainClass="Main"

Run Tests

The test folder contains individual test cases for each pattern. Run the tests using Maven:

mvn test

Dependencies

The project uses the following dependency:

  • JUnit 5: Version 5.11.3 for testing. Specified in the pom.xml file:
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter</artifactId>
    <version>5.11.3</version>
</dependency>

Notes

  1. Pattern Implementation: Each design pattern is implemented in its respective classes with clear separation of concerns.
  2. Test Structure: Each pattern has a dedicated test class for clarity.
