In the above [[Unified Modeling Language|UML]] [[class diagram]], the <code>Creator</code> class that requires a <code>Product</code> object does not instantiate the <code>Product1</code> class directly. Instead, the <code>Creator</code> refers to a separate <code>factoryMethod()</code> to create a product object, which makes the <code>Creator</code> independent of the exact concrete class that is instantiated. Subclasses of <code>Creator</code> can redefine which class to instantiate. In this example, the <code>Creator1</code> subclass implements the abstract <code>factoryMethod()</code> by instantiating the <code>Product1</code> class.
