The abstract factory pattern in software engineering is a design pattern that provides a way to create families of related objects without imposing their concrete classes, by encapsulating a group of individual factories that have a common theme without specifying their concrete classes. [1]
For example, several GoF patterns, like the Factory method pattern, the Builder or even the Singleton are implementations of this concept. The Abstract factory pattern instead is a method to build collections of factories. In some design patterns, a factory object has a method for every kind of object it can create
Design pattern, overview of design patterns in general; Abstract factory pattern, a pattern often implemented using factory methods; Builder pattern, another creational pattern; Template method pattern, which may call factory methods; Joshua Bloch's idea of a static factory method for which Bloch claims there is no direct equivalent in Design ...
Some examples of creational design patterns include: Abstract Factory pattern : a class requests the objects it requires from a factory object instead of creating the objects directly Factory method pattern : centralize creation of an object of a specific type choosing one of several implementations

In a software design pattern view, lazy initialization is often used together with a factory method pattern. This combines three ideas: Using a factory method to create instances of a class (factory method pattern) Storing the instances in a map, and returning the same instance to each request for an instance with same parameters (multiton pattern)
In Factory design pattern Factory should not extend an abstact Factory, whereas in current diagram ConcreteCreator extends Creator. This makes ConcreteCreator/Creator an Abstract Factory design pattern. Wrong. An Abstract Factory describes the interface for creation a set of family objects. Sub-classes override these methods to concrete related ...
