Bertrand Meyer describes in his book " Object Oriented Software Construction (2nd Ed)" qualities that a good object oriented language should have. Java has almost all the features. Ruby is much farther off, which does not mean it is not a good language, I think it’s very good to write some types of programs quickly (should I call them scripts?), syntax is quite nice, but it does lack the following useful features:
