Object-oriented programming, like most interesting developments, builds on some
old ideas, extends them, and puts them together in novel ways. The result is
many-faceted and a clear step forward for the art of programming. An
object-oriented approach makes programs more intuitive to design, faster to
develop, more amenable to modifications, and easier to understand. It leads not
only to alternative ways of constructing programs, but also to alternative ways of
conceiving the programming task
