What problem does abstract factory solve?
The Abstract Factory design pattern solves problems like: How can an application be independent of how its objects are created? How can a class be independent of how the objects it requires are created? How can families of related or dependent objects be created?
Why this pattern is called abstract factory?
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. An Abstract Factory Pattern is also known as Kit.
What is abstract class in design patterns?
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.
When to use the abstract factory pattern?
What is the Abstract Factory Pattern. The Abstract Factory Pattern is used when you want to return several related classes of objects, each of which can return several different objects on request.
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 are the design patterns used in Java?
The various subsets of Design Pattern in Java Adopter Pattern. It helps in joining to unrelated interfaces to work together with the objects. Composite Pattern. Composite patterns are one of the structural design patterns used. Proxy Pattern. It provides a placeholder or surrogate for other objects to control access to it. Flyweight Pattern. Facade Pattern. Bridge Pattern. Decorator Pattern.
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.
