But we prove that this combined sublanguage admits neither static nor the standard dynamic type-checking typical for typed object-oriented languages. An interpretive model is, of course, always possible.

Small Talk, Java, and C# are pure object-oriented languages because you cannot write a program without using objects.

The first approach to implement RAPOOL is to add a layer over an existing object-oriented language. Such a layer has to retrieve user profile and contextual information from role-assignment database.

The Dowl distributed object-oriented language. Commun.

We hope to bring you additional updates as the future of this dynamic object-oriented language continues to unfold.

"The DOWL Distributed Object-Oriented Language" by Bruno Achauer describes another distributed environment, this one based on its own language.

Integrating distribution and object-oriented languages has attracted much attention in recent years.

The syntactical extension, which it brings to an object-oriented language (Eiffel) is the smallest feasible: one new keyword.

The approach to concurrent object-oriented programming presented here is based on extending a sequential object-oriented language with concurrency annotations, leading to a COOL with good reusability properties.

Use an existing object-oriented language and provide concurrency abstractions through external libraries

Many of the available object-oriented languages are either interpreted and slow, have considerable run-time support, or include predefined notions of fundamental parts of an operating system such as processes, synchronization, messages, and exceptions.

Ruby is the creation of Yukihiro Matsumoto, who felt that there was a lack of proper object-oriented languages, and that on most languages it felt like the feature was tacked on.
