Abstract: Aiming at the problem of inconsistencies between the code and the model,this paper presented a consistency detection method based on UML model and the JAVA code.Firstly,the UML class diagram and sequence diagram are formalized and a concept of sequence diagram call graph(SD-CG) is put forward.On this basis,the transformation from the associated relationship between classes to the associated attribute of class and the transformation from the sequence diagram to sequence diagram call graph are completed.Thirdly,based on call graph which is made up of class methods being as nodes and the call relation between them being as edges,to analyze the dynamic behavior in the source code,this paper got the information of Java classes and the method call graph (CG) by the lexical analysis and syntax analysis of Java source code.Then the consistency detection algorithm between UML model and Java source code was designed,including the static information consistency detection and the interactive information consistency detection.At last,we developed a prototype tool which can complete information consistency detection to verify the feasibility and effectiveness of the proposed method.

Key words: UML model,Java code,Sequence diagram call graph(SD-CG),Call graph(CG),Consistency detection
