Expert ,please help explain, how I can get experience in UML ?
Learning the UML is the easy part, just get the book Joachim listed and read it about ten times. The experience takes more time and effort. Start by working on the experience by creating UML diagrams for yourself either at work or at home, even if this is on paper or a white board. The diagrams don't have to include the world in them, just do simple designs with enough so that you know where you are going as you code. Start with simple class diagrams and sequence diagrams (few do more than that anyway). Over time start using the UML as the language in which you talk to your co-works (think of it as a passive shove). If your manager wants to know what you did then draw him a UML picture.
I do understand your situation. I have used UML since 1996 when I trained in OOAD with Craig Larman. However, I too am currently in a company that makes almost no use of the UML and have almost no interest in learning it. However, over time I have forced them to learn the most basic UML because that is the only thing I draw on the white board.
Yes, books are getting rusty. But UML 2.0 was released 5 years ago. And even though I haven't followed the development of UML extensively, I have my doubts that the basics from version 2.0 to 2.2 have changed so dramatically that you cannot use a book for UML 2.0 to get started.
And for someone who never dealt with UML before your provided tutorial is not at all sufficient and the advice that "you don't really need to read books" is in my opinion misleading.
