In a interview I was asked,
Suppose we are going to create a software that runs on both desktop machines and smartphones. Name a software design pattern that could be used to enable the application to create different classes for display at runtime depending on the platform.
I know there are simple solutions to implement this feature in the actual code. For example, in Java I can check the display size and create the suitable class (
DesktopDisplay class) for that display.
But I don't how this is related to the software design; in my opinion, creating suitable class based on runtime platform is an implementation concern rather than a software design issue.
