Comment on Do not start with an Interface by Tim Yen

My experience has lead me away from inheritance. Largely because I have ended up with large unwieldy inheritance structures that needed to be modified and morphed. It sounds like you have ended up with the same situation but using interfaces. Maybe it is just a function of the sheer complexity of the programs we code?

Inheritance always seemed easy in the OO books but in practice it can be a real pain. The same code using interfaces may also be just as much a pain in the long run. I have yet to run into any large unwieldy interface structures, but the more I use them the more I can see it happening.

Hi Bob,

Nice to see that you read my post, your solution was what got me started on this in the first place. Thanks for clarifying about your solution.

FWIW, my solution does generate the #s in order and does find the biggest gap.

Comment on Do not start with an Interface by Ricky Clarkson

Programming to an interface need not allow your users to freely interchange interface and implementation types, if you hide the implementation type behind a factory method (potentially as an anonymous class).

An interface can be annoying when you feel the urge to add static methods - sometimes I use abstract classes only for this reason.

There may be parts of the contract that you cannot specify or check well enough in an interface that makes you rather use a concrete class. For example, the algebraic type Option with implementations Some and None - it is useful to be able to guarantee that Some and None are the only implementations.
