Factory Method pattern

When to use

The Factory Method pattern is useful when we create object without exposing the creation logic to the client. We use a common interface for all objects that will be created:

Shape circle = factory.getShape(ShapeType.CIRCLE);
Shape rectangle = factory.getShape(ShapeType.RECTANGLE);
Shape triangle = factory.getShape(ShapeType.TRIANGLE);

Here getShape(ShapeType type) is a factory method responsible for creating the object of the specified type.

I used a Factory Method pattern here.
