In my experience, Java fans claim that the Interface/Implementation separation feature of OO is provided by the Java Interface structure and Class structure (i.e. the Interface provides the Interface, and the Class provides the Implementation). This seems a very high level viewpoint corresponding to something like a pure virtual class (C++), or abstract tagged type (Ada) rather than what Ada programmers often see as the separation, i.e. the package spec/body. Personally I believe it is a combination of both. Best Regards John McCabe
