Simple Factory Pattern in Java

This project demonstrates the Simple Factory design pattern in Java. It includes an abstract product interface, concrete product implementations, and a factory class to create product instances based on specified types.

Files Description

• Product.java: Defines the Product interface with basic methods that all products must implement, such as use().

• ConcreteProductA.java: Implements the Product interface, defining the behavior of Concrete Product A and overriding the use() method.

• ConcreteProductB.java: Implements the Product interface, defining the behavior of Concrete Product B and overriding the use() method.

• Factory.java: Defines the Factory class, which contains a static method createProduct(String type) that returns the appropriate product instance based on the provided type.

• pom.xml: Maven configuration file that defines the project's dependencies and build settings.

Usage

To use this project, you can call the Factory.createProduct(String type) method with either "A" or "B" to get an instance of ConcreteProductA or ConcreteProductB, respectively. Then, you can invoke the use() method on the product instance to see its behavior.

Build and Run

1. Ensure you have Maven installed on your machine.
2. Navigate to the project directory.
3. Run mvn clean install to build the project.
4. Use the generated classes in your Java application as needed.
