This extension for StarUML(https://staruml.io) support to generate Java code from UML model and to reverse Java code to UML model. Install this extension from Extension Manager of StarUML.
⚠️ This extensions do not provide perfect reverse engineering which is a test and temporal feature. If you need a complete reverse engineering feature, please check other professional reverse engineering tools.
✅ This extension is based on Java 1.7 Specification.
- Click the menu (
Tools > Java > Generate Code...
) - Select a base model (or package) that will be generated to Java.
- Select a folder where generated Java source files will be placed.
Belows are the rules to convert from UML model elements to Java source codes.
- converted to Java Package (as a folder).

- All contained types (UMLClass, UMLInterface, UMLEnumeration) are generated as inner type definition.
