Joose: Java-based Object- Oriented Symbolic Executor

Joose is a Java-based Symbolic Executor which supports modularization of programs into classes. Basic integer and Boolean types are supported along with object types which are parameterized by a specific class expression. The system allows the correctness of the defined classes to be verified with respect to the defined specifications, allows the consistency of the specifications to be checked, and allows Java code corresponding to the defined classes to be generated. This paper aims to give a brief introduction to Joose. The paper consists of a summary of the motivations for the development of Joose, an overview of the Joose IDE, an overview of the Joose languages and discussions of some implementation details and problems encountered in the development of the system. The paper ends by discussing the future of the system.
