Hi,
I have class A and Class B (say)... class B has some methods that class A should use. But class A cannot inherit from B, B cannot be an abstract class or an interface....How do we do that?
all methods should be defined only in B, not allowed to be defined in A...any ideas?

How does it need to use the methods? Without code this is hard to answer.
You can make an instance of B inside A and then use the instance to get at the methods. (Is that what you mean???)

You could put the methods that both are to use in an interface and have both classes implement it.
 
Being a smart alec beats the alternative. This tiny ad knows what I'm talking about:
