What is factory design pattern Java?
The factory design pattern says that define an interface ( A java interface or an abstract class) for creating object and let the subclasses decide which class to instantiate. The factory method in the interface lets a class defers the instantiation to one or more concrete subclasses.
Where is factory design pattern used in Java?
The factory design pattern is used when we have a superclass with multiple sub-classes and based on input, we need to return one of the sub-class. This pattern takes out the responsibility of the instantiation of a class from the client program to the factory class.
What is factory in design pattern?
The factory method is a creational design pattern, i.e., related to object creation. In the Factory pattern, we create objects without exposing the creation logic to the client and the client uses the same common interface to create a new type of object.
What is the advantage of factory design pattern in Java?
Advantage of Factory Design Pattern
Factory Method Pattern allows the sub-classes to choose the type of objects to create. It promotes the loose-coupling by eliminating the need to bind application-specific classes into the code.
