关键词： Java语言   教学改革   教学模式  

摘要： Java程序设计语言在很多高校中都作为学生的第一门程序设计课程讲授,或者作为面向对象程序设计的实现语言讲授。在教学实践中,现行的教学模式主要存在着以下问题:教材建设跟不上技术发展;不能在动手实践方面激励学生编程;考核方法难以评估学生实际的程序设计能力等。为改善上述问题,探索新的教学模式,在教学内容建设、课堂教学、实践教学、及考核方法等方面引入新的方法和技术手段就十分必要。通过这些改革措施,力图提高教学质量,帮助学生打好编程基础。

关键词： Visual contracts   Graph transformation   Model extraction   Dynamic analysis   Reverse engineering   Specification mining  

摘要： Visual contracts model the operation of components or services by pre- and post-conditions formalised as graph transformation rules. They provide a precise intuitive notation to support testing, understanding and analysis of software. Their detailed specification of internal data states and transformations, referred to as deep behavioural modelling, is an error-prone activity. In this paper we propose a dynamic approach to reverse engineering visual contracts from Java based on tracing the execution of Java operations. The resulting contracts give an accurate description of the observed object transformations, their effects and preconditions in terms of object structures, parameter and attribute values, and their generalised specification by universally quantified (multi) objects, patterns, and invariants. While this paper focusses on the fundamental technique rather than a particular application, we explore potential uses in our evaluation, including in program understanding, review of test reports and debugging.

摘要： The development of a procedure supporting automated migration of Java programs to a new set of libraries is explored. Code migration is a common task in modern software projects. For example, it may arise when a project must be ported to a more secure or feature-rich library, a new platform, or a new version of an existing library. This paper presents a procedure for semantics-driven automated migration. A metamodel that applies the formalism earlier proposed by the authors and intended to describe libraries in object-oriented languages was developed for the migration procedure. The formalism specifies a library behaviour by using a system of extended finite state machines (EFSMs). The migration is split into five steps and each step is described in the paper. The procedure applies an algorithm of an equivalent path based on a breadth-first search extended for the needs of the migration task. The proposed procedure is implemented in a prototype of the migration tool. The tool includes modules for extraction of the software execution path, visualization of library models, user interaction, and migration. A library description language was developed for the tool. The prototype was tested by both artificial code and a real-world open source project. The article describes the experiments performed, the difficulties that have arisen in the process of migration of test samples, and how they are solved in the proposed procedure. The HTTP protocol and log library are used as libraries in the experiment. The results of the experiments indicate that code migration can be successfully automated through the developed procedures.
