My system is more complex than the image. In the documentation of UML I couldn't find anything about this. Have you a link where this is explained better?

@ajeje93 Red is absolutely right. You can do it, But whether it makes sense? Only you can decide upon that.

@RedBeard No, I mean when to use a generalization like in the image, but as Thomas pointed out it depends on what you are modeling.
