Currently, i am building an open source project using UML as modeling language.
But i dont't know whether my uml diagram are good or not.
I hope so body can give me suggestions.
https://sourceforge.net/projects/jthumbnailer , you could download my program and my uml-spec. The uml-spec can be viewed by pdf, for detail, you could use visual-paradigm to open the *.vpp file.

Well, basically: If they did help you code the program, they were good; if they didn't they were superfluous; if they interfered with the programming, they were bad. It's really that simple...
So, what are your experiences with the diagrams? (I would be especially interested in your position on wether writing down the use cases helped you in any way.)

Thanks your reply.
I'm fresh on UML. I don't mean to ask other people to write for me, i just hope you could see my project and give me comments, that's that.
I am a fresh graduate student. Now is a programmer. The Jthumbnailer is my own open source project, for practise my analysis skill, i try to model my project by uml.

You're welcome!

I understand.
My point is this: the most important property of UML diagrams is that they were/are helpfull - everything else is secondary. But you are the only one who can tell wether they were/are helpfull for the purpose you created them for (or so it seems to me...).
So, if you'd tell us about your observations regarding the helpfullness of the diagrams, I would very much like to comment...


[...] for practise my analysis skill, i try to model my project by uml.


OK - so how did the diagrams help you understand the problem domain (that is, in analysis)? Did you miss anything? Can you think of different ways to get the same (or even better) understanding of the problem?
In my humble opinion, those questions above are the interesting ones to answer. Unfortunately, you are the only one who can answer them. Again, I would very much like to discuss your observations here.
Kind Regards, Ilja
