Abstract

Simulation is the most widely used technique to prove data refinement. We define forward simulation for a language with recursive classes, inheritance, type casts and tests, dynamic binding, class based visibility, mutable state (without aliasing), and specification constructs from refinement calculi. It is a language based on sequential Java, but it also includes specification and deseign mechanisms appropriate for the construction of programs based on refinement. We show simulation to be sound for data refinement of classes in this language.
