You state that object-oriented programming is an effective way to manage large programs. However, it seems that it might add substantial overhead to relatively
small ones. Since you say that all Java programs are, to some extent, object-oriented,does this impose a penalty for smaller programs?
No. As you will see, for small programs, Java’s object-oriented features are nearly
transparent. Although it is true that Java follows a strict object model, you have
wide latitude as to the degree to which you employ it. For smaller programs, their
“object-orientedness” is barely perceptible. As your programs grow, you will integrate
more object-oriented features effortlessly
