What is the difference between factory design pattern and strategy design pattern?
A factory pattern is a creational pattern. A strategy pattern is an operational pattern. Put another way, a factory pattern is used to create objects of a specific type. A strategy pattern is use to perform an operation (or set of operations) in a particular manner.
Can the strategy pattern be used with the factory pattern?
A Factory class can create new instances in a multithreaded application. Thus, the Strategy design pattern should always be implemented with Factory Method design pattern.
What type of design pattern is Strategy?
Strategy Design Pattern is a type of behavioral design pattern that encapsulates a “family” of algorithms and selects one from the pool for use during runtime. The algorithms are interchangeable, meaning that they are substitutable for each other. The key idea is to create objects which represent various strategies.
What is the difference between the template patterns and the strategy pattern?
The difference between the two is that while the strategy pattern allows different implementations to use completely different ways of the achieving the desired outcome, the template method pattern specifies an overarching algorithm (the “template” method) which is be used to achieve the result — the only choice left …
What is the difference between factory and strategy patterns?
Both patterns use “new” keyword to return an object (factory) or return and algorithm (strategy). Conceptually it seems different, factory is used for differed instantiation of similar group of classes. where as Strategy is used for switching between algorithms. But when i see their examples together, they look quite similar.
What’s the advantage of factory pattern?
Advantage of Factory Pattern – Loose Coupling and Segregation of Responsibilities. Now instead of hard binding the complete logic to decide the nature and shape of the object on the basis of some conditions, you are assigning the responsibility to some other object and hence making the relationship loosely coupled and hence main tenable.
What is the difference between pattern and design?
As nouns the difference between pattern and design is that pattern is model, example while design is a plan (with more or less detail) for the structure and functions of an artifact, building or system. is that pattern is to apply a pattern while design is (obsolete) to assign, appoint (something (to) someone); to designate.
