In my previous article on sequence diagrams I shifted focus away from the UML 14 spec to OMGs Adopted 20 Draft Specification of UML UML 2In this article I will discuss Structure Diagrams which is a new diagram category that.

Here we are taking a class GuruThread2 which will have the main method in it. This is the next installment in a series of articles about the essential diagrams used within the Unified Modeling Language or UML. You would not find it in your source codethe java file as it would be inserted into the code during compilation and exists in class file.

The source code is HERE. Here we are creating an instance of class GuruThread3 which is created in below lines of the code as threadguru1 and we are starting the thread. The steps involved on server side are similar to the article Socket Programming in Java with a slight change to create the thread object after obtaining the streams and port number.
