The Abstract factory pattern provides a way to encapsulate a group of individual factories that have a common theme without specifying their concrete classes. In this pattern, we create an interface or an abstract class with method declarations, and then the concrete classes or subclasses implementing this interface or inheriting the class are responsible for creating instances of the class.
