So far, valuable researches have been conducted on mapping object-oriented specification notations, such as Object-Z, to different object-oriented programming languages, such as C++. However, the results of selecting JVM-based programming languages for mapping have not covered most of basic Object-Z structures. In this paper, the Groovy language, as a dynamic JVM-based language, is selected to overcome some of the existing limitations. As the main contribution, the rules required for mapping Object-Z specifications to executable Groovy code are introduced. The proposed rules cover notions such as multiple inheritance, inverse specification of functions, functions defined on generic definitions, and free type constructors. These notions have not been covered in previous methods for formal program development from object-oriented specifications, regardless of the selected formal specification language and target programming language. In addition, in this paper, the parallel composition construct is mapped to a parallel, executable code to improve the faithfulness of the final code to the initial specification. We also introduce a mapping rule for the class union construct, which has not yet been provided for any JVM-based language. Unlike previous works, instead of presenting the mapping rules in terms of natural languages, we present them in terms of some formal mapping rules.

Due to the popularity of object-oriented programming approaches, there is a growing interest in utilizing object-oriented concepts, such as encapsulation and reuse, when applying formal methods. The main contribution of this paper is to review and compare existing formal methods to develop object-oriented programs from formal speci cations. The secondary contribution is providing a comparison between widely used object-oriented formal speci cation languages. The results of this paper can be utilized by researchers wishing to know what open problems are outstanding in the areas of formal, objectoriented speci cation and program development. Our ndings are also useful for those who are looking for proper speci cation languages and program development methods to specify and develop object-oriented programs formally. In addition, the provided criteria are suitable for evaluating numerous object-oriented formal speci cation languages that are under development, either by extending existing formal approaches or formalizing informal OO-methods. As one consequence of this work, it can be mentioned that among formal speci cation languages, OZ and VDM++ support OO concepts more strongly in comparison to VDM++ and UML-B. Program development methods based on OZ have less tool support. Finally, most proposed methods for formal, object-oriented program development have been evaluated using only case studies, rather than employing formal approaches.

Object-Z is an extension of Z which provides specific constructs to facilitate specification in an object-oriented style. A number of contributions have been made so far to animate Object-Z with various object-oriented programming languages. However, none of the existing animation methods present their mapping rules formally. Also, none of these animation methods prove the correctness of their mapping rules. In our previous work, we informally presented an animation method to map Object-Z specifications into C++ code. In this paper, we propose a formal mapping from Object-Z specifications to C++ code. We also prove the correctness of the given mapping rules.
