Neither will it generate code for abstract methods. You can get sequence numbers from the message properties inspectors. You can also get them by double clicking the messages in the diagram. Below is the completed sequence diagram, with three messages in boldface. Together sequence diagrams put boldface type on messages that are invoked as a result of creating code via Generate Implementation .
Sequence diagrams can give structure to code.
But it's up to you to finish the details. Correct logic errors as you see fit. Creating sequence diagrams from existing code Together can generate sequence diagrams from code that has no syntax errors. As a preliminary step to your next task, you should Make the project as an error check. Show every class from the AirlinePD package.
