Automatic Generation of Java Code From UML Diagrams Using UJECTOR

In recent years, the significance of automated generation of object-oriented code from UML diagrams has increased due to its benefits, such as, cost reduction and accuracy. Consistency checking between UML diagrams, and ensuring accuracy, maintainability, efficiency, and completeness of the generated code are the main concerns in this area. This paper extends the work on a tool called UJECTOR for automatic generation of executable Java code from UML diagrams. A set of three UML diagrams, i.e., class diagram, sequence diagrams and activity diagrams are input to the tool to generate completely executable Java code automatically. The object-oriented code structure is built from class diagram, methods' flow of control is created through sequence diagrams, and object manipulations are included by activity diagrams from the implemented approach in UJECTOR.
