Ummm. Does anyone know what an interface mean in this particular lesson context or in the context of Polymorphism ?
I would appreciate it if anyone could say a thing or two, regardless of how little it may be, pertaining to my question. Thank you.


Hey there, since writing this comment, have you gained some insights on this topic? I would greatly appreciate any input.

I’m guessing interface here means a common reference which multiple classes implement (possibly in different ways). But yeah, very unsure to be honest.

i found this, even though it’s been a while. i hope this helps other people who might wonder too.

in Computer Science, an interface is:
Device that allows communication between two elements of a computer system.

I admit it’s confusing the way the lesson uses ‘interface’. We are given a clue: ‘interface in the general meaning’. My understanding is that ‘interface’ here means how ‘we interact with’ objects.
