Client Code (Application):?

• The Application class accepts an IUIFactory in its constructor. This

means the client code can choose which concrete factory (Windows or Mac)

to use without changing the Application class itself.

public class Application
{
private readonly IButton _button;
private readonly ICheckbox _checkbox;
public Application(IUIFactory factory)
{
_button = factory.CreateButton();
_checkbox = factory.CreateCheckbox();
}
public void Render()
{

_button.Render();

_checkbox.Render();

}
}
