Factory Method Design Pattern: Coding ExampleIn factory method design pattern mainly three classes/interfaces are involved, first, the factory class that creates an object from a given class hierarchy, second, a
The Factory method works just the same way: it defines an interface for creating an object, but leaves the choice of its type to the subclasses, creation being deferred at run-time. A simple real life example of the Factory Method is the hotel. When staying in a hotel you first have to...
ExampleThe Factory Method defines an interface for creating objects, but lets subclasses decide which classes to instantiate. Injection molding presses demonstrate this pattern. Manufacturers of plastic toys process plastic molding powder, and inject the plastic into molds of the desired shapes. The ...
Factory Method: creation through inheritance. Prototype: creation through delegation. Often, designs start out using Factory Method (less complicated, more customizable, subclasses proliferate) and evolve toward Abstract Factory, Prototype, or Builder (more flexible, more complex) as the designer discovers...

You will learn about the Factory Method design pattern and its implementation in C# along with real-world example to understand how you can use this pattern in your application. Factory method pattern is a creational design pattern that provides an interface for creating objects but allows subclasse...
Simple Factory:Strictly speaking, it’s not a design pattern, but a technique we use very often. It encapsulates the object instantiation process. Factory Method:Defines an interface for creating an object, but let’s the classes that implement the interface decide which class to instantiate. The...
We will create 5 classes to implement this pattern. Super Class (CrunchfiyCompany.java) Super class in factory pattern can be an interface, abstract class or a normal java class. For our example, we have super class as abstract class with overridden toString() method for testing purpose. ...
