You can create static sequence diagram views of methods (operations), including signatures, in Java™ classes and interfaces to visually represent and explore behaviors and interactions in Java applications.
A static UML sequence diagram view is a topic diagram, which has a .tpx file name extension. You can refresh static sequence diagram views of Java methods to reflect the latest changes in the source code. You can convert them to editable UML sequence diagrams, which has a .dnx file name extension, that you can use to understand and develop behaviors and interactions between Java classes and interfaces.
