Hello,

is there some point to override used in:

Code: Alles auswählen

override def eat(food: this.SuitableFood) : Unit = {}

Maybe I am missing something but the method to be overridden is within an abstract class an has no body whatsoever. So I couldnt figure out why a class inheriting the abstract class should override the method eat when by default you are forced to create an implementation. Thank you.

Here, "override" is used to get informed by the compiler if the method no longer overrides something. I.e., it is an instance of "defensive programming".
