Need some Java advanced concept for seminar

Dear all,
i need some java latest concepts to present a seminar.Kindly suggest me some useful and easy topics to learn

Thanks for your kind consideration in advance

What do you mean by "concepts"? Are you intending to talk about language semantics, aspects of the API, or capabilities of the platform?

(NB: I've edited your subject - please don't shout in future topics).

hi,
thanks for your reply. I need something related to web services(like as JSP/SERVLET) that are able to explain with simple demos.

Tricky - advanced concepts are generally hard to explain with simple demos :-)

But I'm confused - this is the JDBC forum, yet you mention web services, and then servlets/JSP (which have nothing to do with web services, and everything to do with web apps). Can you be more precise about what you're looking for?
