The return type of method parameters are shown after the colon following the parameter name. The rules and semantics of a model are expressed in English, in a form known as object constraint language. The figure below shows an example of inheritance hierarchy. This book is a collection of tutorial notes and sample codes written by the author while he was learning UML (Unified Modeling Language) himself. Design model development will typically start with heavy emphasis on the specification perspective, and evolve into the implementation perspective. Where two or more paths converge back into the same path, insert a join node. I will consider it as a token of appreciation from you.
