Extension of Automatic Visualization Tool "Avis" for Large Scale Programs

As the demand for software is increasing more rapidly, the demand for the number of programmers is escalating. It is important to educate programmers in order to increase the number of skillful programmers. In this research, the automatic visualization tool "Avis" has been developed for Java to educate the programmers. Avis consists of three parts: "Parser," "CF-Generator," and "P-Generator." But large scale programs are not applied to P-Generator because P-Generator gets into overflow by excessive declaration of array. In this paper, the data structure of P-Generator is extended so that it can be applied the large scale programs. Consequently, the practicality of Avis improved because more Java programs can be applied to Avis. Moreover, the usefulness of Avis has been confirmed by using Avis for students of University of Miyazaki.

In object-oriented programs, such as Java, a system is executed by sending and receiving messages between the objects generated in run-time. However, it is difficult to understand what message communication an object actually is executed only by the source code. This research aims at the reliability improvement of Java programs and the understanding support of the behavior of the Java programs, and visualizes the execution history of the Java programs by using a sequence diagram. Java programs are analyzed dynamically and method call relations between objects are expressed on a sequence diagram based on the execution history. Values of arguments and return values when a method call occurs are also displayed on the same sequence diagram. Consequently, an understanding of the behavior and improvement of reliability of programs are promoted, because the message communication by objects can be shown visually.

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：The Institute of Electronics, Information and Communication Engineers
As the demand for software is increasing more rapidly, the demand for the number of programmers is escalating. It is important to educate novice programmers in order to increase the number of skillful programmers. In this research, the automatic visualization tool "Avis" has been developed for Java to educate the novice programmers. But, most Java programs are not applied to Avis because Avis can not accept the structure of classes. Avis consists of three parts : "Parser,""FC-Generator," and "P-Generator." Parser and FC-Generator have been enhanced to apply the structure of classes. In this paper, P-Generator is extended so that it can be applied the structure of classes for Java to. Consequently, by using Avis, the novice programmers can understand the behavior of Java programs easily.

UML (Unified Modeling Language) is often used at the requirements analysis and the design. However, in describing source codes from models, it takes time and artificial mistakes may occur. In this research, the conversion rules for programming support have been extracted from UML diagrams to Java source codes. It is possible for the conversion rules to improve productivity and reliability of software. In this paper, new conversion rules have been extracted, a prototype of conversion tool that automatically generates Java source codes from UML diagrams based on the extracted conversion rules has been implemented, and it is confirmed that the conversion rules are useful.

The demand for software is increasing more rapidly than ever. The demand for the programmers is increasing. It is important to educate novice programmers in order to increase the number of skillful programmers. This paper describes a prototype of an automatic visualization tool "Avis" for Java programs to educate the novice programmers to the programming. "Avis" generates a flowchart and paths, from the source code. Since "Avis" visualizes correspondence of the statements of the source code to the flowchart and paths, the novice programmers can understand the behavior of Java programs easily.

Proposal of a method to support testing for Java programs with UML

There is an increasing need for effective testing of software for complex safety-critical applications. This paper proposes a supporting method of testing for Java programs by using Unified Modeling Language (UML) in order to improve the reliability of them. The correspondences of source codes in Java and elements of a class diagram, a sequence diagram, and a statechart diagram have been extracted. By using the extracted correspondences as test items in testing, it becomes possible to test effectively the specification of software, the structure of Java programs, the flows of processing of a system, and the flow of transition between states. Moreover, in order to confirm the validity of the proposed method, a prototype tool to support testing for Java programs is implemented. The inputs of this prototype are three diagrams, and the outputs are test items generated from, the extracted correspondences. As an example, a source code of blackjack game in Java has been tested by using the test items outputted from the prototype. It has been possible to test 67.2% of the number of lines in the whole source code. © 2005 IEEE.

In Java, a method or a variable might be called as an object. The method is executed when it is called by the object. This call relation is made difficult to understand the behavior of the program. This research aims at supporting the understanding of the behavior of Java programs. In the paper, the control flowgraph which includs information of call relations among objects is generated. By visualizing a program with the control flowgraph, the time needed to understand the behavior of the program is reduced.
