hi there

i need to few stuffs about JVM... The use of a virtual machine such
as JVM to execute programs leads to overhead that slows down the
execution of the executed programs.

Compared to what? To running "the same" program without
a virtual machine? Without an O/S?

can anyone explain in technical
terms the reasons for this overhead and all solutions that are
implemented to reduce such overhead.

No, because "overhead" is itself not a technical term. Some
quantity of resource is expended in the course of getting something
done, and you may choose to label some part of the expenditure as
"overhead" -- but somebody else could choose differently, and I'm
not aware of any objective criterion that could say which of you
(if either) was right. I think that if you come up with a rigorous
definition of "overhead" (for your purposes), you will already have
answered all the hard parts of your question.
