In the video, I discuss when and how to implement an abstract factory pattern. Abstract Factory Design Pattern in Java Back to Abstract Factory description Abstract Factory classes are often implemented with Factory Methods, but they can also be implemented using Prototype. Simple Factory: Strictly speaking, it’s not a design pattern, but a technique we use very often.It encapsulates the object instantiation process. Abstract Factory patterns work around a super-factory which creates other factories. The Factory Method Pattern is also known as Virtual Constructor. Factory Method: creation through inheritance. Abstract factory pattern implementation provides us a framework that allows us to create objects that follow a general pattern. What Factory Design Pattern Is The Factory Design Pattern is a commonly used design pattern where we need to create Loosely Coupled System. This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object. Basically, it comes under Creational Pattern and it is used to create instance and reuse it. Each generated factory can give the objects as per the Factory pattern. I recently uploaded a video on YouTube for abstract factory design pattern. So, this is the reason that Abstract Factory Pattern is one level higher than the Factory Pattern. I have also discussed what is the difference between the factory pattern and abstract factory design pattern. Abstract Factory Pattern . All the wrapper classes like Integer, Boolean etc, in Java uses this pattern to evaluate the values using valueOf() method. Abstract Factory Pattern by Example. So at runtime, abstract factory is coupled with any desired concrete factory which can create objects of desired type. Typically, when the underlying implementations or mechanisms of object creation vary a lot but those implementations can be placed under the same top level umbrella & you need same public API to access them, there is a good chance that you need Abstract Factory Method design pattern. Factory Method Pattern. Abstract Factory Pattern says that just define an interface or abstract class for creating families of related (or dependent) objects but without specifying their concrete sub-classes.That means Abstract Factory lets a class returns a factory of classes. Factory Pattern is based on real time factory … Factory Method: Defines an interface for creating an object, but let’s the classes that implement the interface decide which class to instantiate.The Factory method lets a class defer instantiation to subclasses. Let’s remodel the vending machine as shown in the image below. Abstract Factory Design Pattern Video Tutorial. This tutorial highlights implementing the abstract factory design pattern in your Java projects, focusing on implementation, structure, and helpful examples. Real-time examples This design pattern has been widely used in JDK, such as 1. getInstance() method of java.util.Calendar, NumberFormat, and ResourceBundle uses factory method design pattern. In other words, subclasses are responsible to create the instance of the class. 2. In Abstract Factory pattern an interface is responsible for creating a factory of related objects without explicitly specifying their classes. A Factory Pattern or Factory Method Pattern says that just define an interface or abstract class for creating an object but let the subclasses decide which class to instantiate. For our understanding of this pattern, we will take a simple example of different types of Bank Accounts. Abstract Factory might store a set of Prototypes from which to clone and return product objects. As we previously noted, the abstract factory pattern allows us to easily re-use components as abstract classes and enforce specific concrete subclasses to be used as part of a component family.
