Design pattern in object-oriented programming

The Factory Pattern is a design pattern that facilitates object creation in object-oriented programming

Benefits of using the Factory Pattern

Reducing coupling between classes

The Factory Pattern promotes a coding style that reduces the dependency between classes, leading to more maintainable and flexible codebases

Increasing code reusability

By coding to an interface rather than a specific class, the Factory Pattern allows for the reuse of code and the introduction of new object types without altering existing code

Improving scalability of software

The Factory Pattern enables the creation of objects in a controlled and modular manner, making software more scalable and adaptable to changing environments

Practical applications of the Factory Pattern

The Factory Pattern is commonly used in real-world applications to manage and create objects in a controlled manner, such as in document editors and GUI libraries

Use of the Factory Pattern in Java

Java's strong emphasis on object-oriented principles makes it an ideal environment for implementing the Factory Pattern

Structure of the Factory Pattern in Java

Abstract base class or interface

The Factory Pattern in Java involves defining an abstract base class or interface with a factory method

Concrete subclasses

Concrete subclasses implement the factory method to instantiate specific types of objects

Advantages of using the Factory Pattern in Java

The Factory Pattern in Java simplifies code management and adaptability, adheres to the principle of 'separation of concerns', and aids in managing the complexity of creating objects with intricate configurations

Differences between the Factory Pattern and Abstract Factory Pattern

While both patterns involve object creation, the Factory Pattern focuses on creating a single object, while the Abstract Factory Pattern is concerned with creating families of related objects

Benefits of using the Abstract Factory Pattern

Higher level of abstraction

The Abstract Factory Pattern provides a higher level of abstraction by allowing the creation of multiple families of related objects without altering existing code

Adherence to the open/closed principle

The Abstract Factory Pattern allows for the addition of new product families without changing existing code, adhering to the open/closed principle
