encapsulation
polymorphism
inheritance
composition
is-a
has-a
loose-coupling
high-cohesion


i hava a little headache on those conceptual OO puzzles below,

what are the dependancies and oppositions between one another?
what are benefits and trade-offs from each of them?

Thanks in advance for your insightful clarification!
