Jabarkan Class without inheritance dari Class (élmu komputer) dalam bahasa sunda

Not every language that both supports objects and classes is generally seen as object-oriented. Examples are éarlier versions of Visual Basic, which lack the support for inheritance. The lack of inheritance severely impairs the full practice of object-oriented programming. Those languages, sometimes called "object-based languages", do not provide the structural benefits of statically type checked interfaces for objects. This is because in object-based languages it is possible to use and extend data structures and attach methods to them at run-time. This precludes the compiler or interpreter from being able to check the type information specified in the source code as the type is built dynamically and not defined statically. Most of these languages allow for instance behaviour and complex operational polymorphism (see dynamic dispatch and polymorphism).
