objects and methods

[meediake]

i have a code similar like this one:

class first
{
     function some1()
    {
         //here I want to use a function named second()
    }
}

class other extends first
{
     function second()
    {
           //bla bla
    }
}

Is that possible somehow?

Have you tried it?

[superwormy]

Only if you make an instance of class other in class first...

But really... what you're doing isn't very pretty, are you sure you need to? It seems awefully wierd of a thing to do...?

Maybe you can post WHY you need to do that?

As Weedpacket suggested, it will work.

You should never have any instances of "first" though, only "other" and other subclasses of first.

This is a fairly common thing in object-oriented programming. "first" is what we call an "abstract class". It defines common fields and methods for its subclasses, but depends on subclasses to complete the implementation. A subclass of an abstract class is said to be "concrete" (unless it too is abstract).
