Example Abstract Factory Pattern Java

Abstract Factory pattern is robust and avoid conditional logic of Factory pattern. Abstract Factory Design Pattern Examples in JDK.

Design Patterns Strategy Pattern What Is Strategy Software Design Patterns Pattern Design

For example we have two groups of utensils Microwave safe and non microwave.

Example abstract factory pattern java. So that the client does not need to worry about the exhausting object creation. You can already look deeper into different real time examples of abstract factory in JDK distribution. In other words We can also say that the abstract factory is a factory of related objects.

Abstract Factory patterns work around a super-factory which creates other factories. In this article Ill demonstrate a small-but-complete example of the Factory Pattern also known as the Factory Design Pattern and Factory Method implemented in Java. The Abstract Factory is rarely being used in java library From the XML API there is one example of.

These objects have some meanings in group. Public interface Animal public void setAgeint age. Abstract Factory pattern is factory of factories and can be easily extended to accommodate more products for example we can add another sub-class AsusLaptop and a factory AsusProcessor and AsusStorage.

So at runtime abstract factory is coupled with any desired concrete factory which can create objects of desired type. In order to understand the concept of Abstract Factory in Java please take a look at the UML diagram for the Abstract Factory pattern. The abstract factory pattern is a creational pattern which provides a way to encapsulate a group of individual factories that have a common purpose or.

Types of Design Pattern 1. Many frameworks and libraries use it to provide a way to extend and customize their standard components. Actually the application should also be implemented against an abstract factory interface without even knowing about the factory implementation.

Here are some examples from core Java libraries. Abstract factory design pattern is used to mange different object types of same family. Therefore it is best to apply abstract factory pattern for the example.

This tutorial highlights implementing the abstract factory design pattern in your Java projects focusing on implementation structure and helpful examples. In other word we can say that we have some objects and they are grouped. DocumentBuilderFactorynewInstance TransformerFactorynewInstance There are other similar examples but the need is to have the feel of the abstract factory design pattern which you must have got till now.

For testing this pattern here it is an example. Two objects from different group can not be mixed. This is the abstract factory for the rest of the sub-factories.

All the object should belong to same family but they are of different categories. Solution using abstract design factory. Its main purpose is to provide a way to create a related set of concrete objects without knowing about their concrete implementation.

Let see the GOFs representation of Abstract Factory Pattern. The generated factory from an abstract factory pattern always generates the object as per the factory design pattern. Abstract Factory pattern is factory of factories and can be easily extended to accommodate more products for example we can add another sub-class Laptop and a factory LaptopFactory.

Abstract Factory pattern is. This base class provides interfaces to get concrete products using the concrete factories. Abstract factory pattern implementation provides us a framework that allows us to create objects that follow a general pattern.

UML class diagram example. The Abstract Factory Design Pattern is a creational pattern. The Abstract Factory pattern is pretty common in Java code.

In this example Ill create a simple dog factory that can return a variety of Dog types where the Dog that is returned matches the criteria I specify. Abstract Factory Design Pattern Provides a way to encapsulate a group of individual factories 2 Independent families of products can be used Reveals interfaces hides implementation 3 12. We can identify classes and interfaces for the example as below.

In which a common interface is implemented throughout the abstract factory and its factories.
