What is Abstract Factory in Java?
Abstract Factory is a creational design pattern, which solves the problem of creating entire product families without specifying their concrete classes. Abstract Factory defines an interface for creating all distinct products but leaves the actual product creation to concrete factory classes.
What is the purpose of the Abstract Factory pattern?
The purpose of the Abstract Factory is to provide an interface for creating families of related objects, without specifying concrete classes. This pattern is found in the sheet metal stamping equipment used in the manufacture of Japanese automobiles.
What is Abstract Factory design?
Abstract Factory is a creational design pattern that lets you produce families of related objects without specifying their concrete classes.
What is the difference between factory and Abstract Factory?
The main difference between a “factory method” and an “abstract factory” is that the factory method is a single method, and an abstract factory is an object. The factory method is just a method, it can be overridden in a subclass, whereas the abstract factory is an object that has multiple factory methods on it.
When would you use Abstract Factory over factory method?
The idea behind the Factory Method pattern is that it allows for the case where a client doesn’t know what concrete classes it will be required to create at runtime, but just wants to get a class that will do the job while Abstract Factory pattern is best utilized when your system has to create multiple families of …
Why do we need abstract factory design pattern?
Abstract factory pattern implementation provides us a framework that allows us to create objects that follow a general pattern. So at runtime, abstract factory is coupled with any desired concrete factory which can create objects of desired type. UML class diagram example for the Abstract Factory Design Pattern.
What is abstract factory method?
An Abstract Factory is a class with several Factory methods. So basically, an Abstract Factory class has a collection of different Factory Methods to create different desired Concrete objects. Each concrete factory sub-class implements the Factory methods for a particular family of products.
What are disadvantages of abstract factory design pattern?
However, the main drawback of the abstract factory pattern, like most design patterns, is that there is an increase in complexity in the code, and an increase in the number of classes required for the code. Although, this disadvantage is well known when applying design patterns for it is the price to pay for gaining abstraction in the code.
What is an abstract factory?
Abstract Factory is a creational design pattern that lets you produce families of related objects without specifying their concrete classes.
