The factory design pattern is a commonly used creational design pattern that provides an interface for creating objects but allows subclasses to decide which class is instantiated. This pattern is accomplished by delegating the instantiation task to subclasses to achieve the purpose of decoupling. In Java, the factory pattern is often used to create complex objects or combinations of objects.
In this article, we will explore how to implement the Factory design pattern in Java and provide an example to demonstrate its usage.
First, let's define a simple interface that represents the object we want to create:
public interface Product {
void operation();
}
The interface contains only one operationmethod named, which is used to perform operations on the object.
Next, we create two concrete classes that implement Productthe interface:
public class
