The Factory Method design pattern provides a solution:
Define a separate operation (factory method) for creating an object.
Create an object by calling a factory method.
Describing the Factory Method design in more detail is the theme of the following sections.
See Applicability section for all problems Factory Method can solve.

• The key idea in this pattern is to create an object in a separate operation so that subclasses can redefine which class to instantiate if necessary.
• Define a separate factory method:
  
  • The pattern calls a (separate) operation that is (exclusively) responsible for "manufacturing" an object a factory method. [GoF, p108]
• Create an objects by calling a factory method
  (Product product = factoryMethod()).
  
• This enables compile-time flexibility (via subclassing).
  Subclasses can be written to redefine the way an object is created.
• "People often use Factory Method as the standard way to create objects, but it isn't necessary when the class that's instantiated never changes […]" [GoF, p136]
• Note that the Factory Method pattern can be implemented differently (abstract, concrete, or static factory method). See Implementation.
