    Default Question about interfaces

    I really just suspect this, but I'm asking to confirm one way or the other.

    In the study books I have read about interfaces, all of the examples I have seen so
    far show the interface being created, then the functions placed in whatever class
    they seem to be working with at the time. Yet they say that you create interfaces
    so that they can be used by more than one class or project type. This leads me to
    believe that perhaps in the real coding world, you would actually create the interface
    and the implementation separate, and then just use it in whatever class you are
    working on as the need arises. The reason I think this makes more sense is it
    seems a cleaner approach as opposed to mixing it in with a class that you could
    very well end up discarding, which would then break the functionality of any other
    classes you used the interface in. Am I correct?

    You should at least fix the line breaks when you copy and paste text into a forum.
    If you don't understand my answer, don't ignore it, ask a question.

    You have drawn the wrong conclusion; I did not paste this in. I use a 42" television
    as my computer monitor . . . . hence the "wideness".

    Yes implementation can be many for a single interface. For Example you can have an interface called car and in turn this interface could be implemented by many like Ford,Toyota,Honda etc.
