Factory Method Design Pattern in Java – GeeksforGeeks
Product Details: Factory Method Design Pattern is a creational design pattern that defines an interface for creating an object, allowing subclasses to decide which class to instantiate.
Technical Parameters:
– Abstract Product Class or Interface
– Concrete Products implementing the Product interface
Application Scenarios:
– JDBC uses factories to create connections and statements.
– Frameworks like Spring and Guice utilize factories for managing beans.
Pros:
– Separates object creation from client code, enhancing flexibility and maintainab…
– New product types can be easily added without altering client code.
Cons:
– Adds more classes and interfaces, complicating understanding and maintenance.
– Client code must be aware of concrete subclasses to make accurate factory calls.
Factory Method – refactoring.guru

Frequently Asked Questions (FAQs)
What is the factory design pattern?
The factory design pattern is a creational design pattern that provides an interface for creating objects in a superclass but allows subclasses to alter the type of created objects. This pattern helps encapsulate the instantiation logic, making your code more flexible and easier to maintain.
When should I use the factory design pattern?
You should consider using the factory design pattern when your code needs to create multiple related objects without specifying their concrete classes. It’s particularly useful when the creation process is complex or when you want to promote loose coupling between your classes.
What are the benefits of using the factory design pattern?
Using the factory design pattern offers several benefits, including improved code readability, easier maintenance, and enhanced flexibility. It allows you to manage object creation more effectively and supports adherence to the Open/Closed Principle, making your code more adaptable to changes.
What is the difference between a factory method and an abstract factory?
A factory method is a method that returns an instance of a class, typically defined in a single class. An abstract factory, on the other hand, is a factory of factories, providing an interface to create families of related or dependent objects. This means abstract factories can create multiple types of objects.
Can the factory design pattern be used in any programming language?
Yes, the factory design pattern can be implemented in any programming language that supports object-oriented programming. Whether you’re using Java, C, Python, or any other OOP language, you can leverage this pattern to manage object creation and improve your code structure.
