Teaching Program Specification and Verification Using JML and ESC/Java2

摘要

The paper summarises our experiences teaching formal program specification and verification using the specification language JML and the automated program verification tool ESC/Java2. This technology has proven to be mature and simple enough to introduce students to formal methods, even undergraduate students with no prior knowledge of formal methods and even only very basic knowledge of (Java) programming. However, there are some limitations on the kind of examples that can be comfortably tackled.
