A factory method Pattern

A factory method handles object creation and encapsulates it in a subclass. This decouples the client code in the superclass from the object creation code in the subclass.

public abstract class PizzaStore {

       public Pizza orderPizza (String type ) {             Pizza pizza;             pizza = createPizza ( type );             pizza.prepare();             pizza.bake();             return pizza();

        }

  protected abstract Pizza createPizza (String type) ;

}
