Books Quote by Kirk Knoernschild
““Those readers new to object orientation typically assume a close relation exists between inheritance and reuse. We want to debunk this myth immediately. Though reuse is touted as a benefit of object orientation, it is in fact a goal. Reuse cannot be taken for granted, nor is it guaranteed. In reality, achieving reuse requires a lot of effort and discipline, and we'll spend a lot of time in this book talking about this aspect of object orientation.””
