How abstract factory pattern works in Java?

How abstract factory pattern works in Java?

This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object. In Abstract Factory pattern an interface is responsible for creating a factory of related objects without explicitly specifying their classes.

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 key strategy in the 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.

What is difference between factory method 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.

What is difference between factory method and Abstract Factory?

How does an Abstract Factory work?

Abstract Factory patterns work around a super-factory which creates other factories. This factory is also called as factory of factories. In Abstract Factory pattern an interface is responsible for creating a factory of related objects without explicitly specifying their classes.

What is the difference between factory method and Abstract Factory?

What problem does abstract factory pattern 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?

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.

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 abstract factory in design patterns?

When to use abstract class and interface in Java?

“Use” of Abstract Class and Interface in Java – While an interface is ideal for type declaration, an abstract class is best suited for code reusability and evolution perspective. An interface looks like a class, but it is not a class.
