I'm creating class diagrams in UML, and can't figure out how to add 'void' as a return type. Can anyone point me in the right direction?

When you add a new operation to the class, by default the return type is void. You can verify it from menu UML2 > Generate Java. The generated java class for the uml diagram will have the return type as void for the operation.

Let us know if you any questions.
