Object Oriented Programming
... A quick diversion from OOP here! At this point you might think it doesn't matter whether you use C++ or Java, they both implement object oriented technology. Well, C++ can be used to design programs without implementing any objects; C++ can be used as an extended C. In Java, you must implement any n ...
