As you probably know dependency injection can help us to develop better software which has more separation of concerns and many more benefits that comes with it.</p> <p>All that aside back to the main topic, what has factory pattern got to do with it?</p> <h2 id="problem">Problem</h2> <p>Lets assume that we have class A thats depended on class B, we declare our dependency on an abstraction of which class B provides the implementation lets call the abstraction B&rsquo;, so that our code is not depended on a concrete implementation and we inject the B class as the implementation while/after instantiation of an object of type A, in this way we have loosen our dependency.</p>
