I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

i got idea about refelection. But what is
dynamic class loading  and  byte code injection. How dynamic class loading  and  byte code injection are different from reflection?
please advise
dynamic class loading falls under reflection.

Byte code injection is injecting code into a class file during the compile phase.
Usually done by annotating your class with things such as  getter/setter generation.
