Enhancing The Expressiveness Of The Cleanjava Language, Melisa Vela, Yoonsik Cheon

Departmental Technical Reports (CS)

The CleanJava notation is based on the Java expression syntax with a few extensions, and thus its vocabulary is somewhat limited to that of Java. This often makes it difficult to specify the rich semantics of a Java program in a succinct and natural way that is easy to manipulate for formal correctness reasoning. In this paper we propose to make the CleanJava language more expressive by supporting user-defined mathematical …
