In [[class-basedobject oriented programming]], the '''factory method pattern''' is a [[creational pattern]] that uses factory methods to deal with the problem of [[object creation|creating objects]] without having to specify the exact [[class (computer programming)|class]] of the object that will be created. This is done by creating objects by calling a factory method—either specified in an [[Interface (object-oriented programming)|interface]] and implemented by child classes, or implemented in a base class and optionally [[method overriding|overridden]] by derived classes—rather than by calling a [[Constructor (object-oriented programming)|constructor]].
