Class-based object-oriented languages are OO with classes. Instances of objects are made by inheriting a master class. The original one was Simula.
Language with objects, interfaces, parameterized types, no inheritance, operator overloading, generators, static instantiation, compiled to C; descriptions, source code, examples, compiler.

Interpreted, with 1 type (all is data) only, made with Java; can be used as strings of its own code or as Java objects, code (even 1-line program) can write or modify other code; main purpose: write artificial intelligences that modify (parts of) themselves or write other code.
Object-oriented extension to C language. Solves many of the problems associated with C++.
Project to create object-oriented language that is easy to learn for beginners.
Experimental, innovative, object-oriented, interpreted language, and programming environment LavaPE; edits programs via syntax-sensitive point-and-click style structure editors, not text editors; parameterized (virtual) types, refactoring, static checks.
Ruby-like expressiveness + static type checks, like Haskell. [Open Source, GPL]
Practical OO language: Ruby-like expressiveness with Haskell-like static type checks. Coded in ML, runs on Linux. [Open Source, GPL]
OO language based on, integrated with, Java (compiler emits Java bytecode); features of functional programming, implements state-of-art results from academic research, for more expressivity, modularity, safety. [Open source, GPL]
Interactive geomatic object-oriented language for spatial modeling, image processing, remote sensing, digital photogrammetry, geographic information system (GIS), geodesy, and surveying and mapping.
Syntax similar to C++, Java, advanced high level features: strong type system, automatic memory management, global code optimization. Development website, has some documentation, forum, announcement from developers, sources. [Open source, GPL]
Full-featured, semi-dynamic object-oriented language. [Open source, GPL]
Compiled object-oriented language fully based on XML syntax; conforms to XML version 1.0 specification as published by W3C. Descriptions, documents, FAQ, downloads, links. [Open Source, LGPL]
High level, simple, Java-style, object-oriented, compile time error checking; native support for major concepts of time, state, properties, networking, which few languages address, to greatly simplify code. Mainly for games.
